The document discusses the Jominy end quench test for determining the hardenability of steels. It describes how a standardized test sample is austenitized and then quenched at one end with water. Hardness measurements along the length provide a hardenability curve, with greater hardness penetration indicating higher hardenability. The cooling rate decreases with distance from the quenched end, allowing simulation of a range of cooling rates. Comparison of curves for different steels establishes their relative hardenability.
The document discusses heat treatment and metal fabrication processes. It begins by defining heat treatment as a method to alter the physical and chemical properties of a material through heating and cooling. It then describes various metal fabrication techniques like forging, rolling, extrusion, and casting. The remainder of the document discusses heat treatment processes for steel like annealing, normalizing, and stress relief annealing. It explains how these processes are used to achieve desired microstructures and properties without changing the shape of the material.
- Heat treatment is a method used to alter the physical and chemical properties of materials by heating or cooling them to extreme temperatures.
- Common heat treatments for steels include annealing, normalizing, and spheroidizing to produce specific microstructures like pearlite that improve properties like strength and machinability.
- Quenching involves rapidly cooling steel to form hard martensite, while tempering at lower temperatures increases toughness but decreases hardness.
- TTT and CCT diagrams are used to determine the microstructures that form during continuous cooling of steel based on factors like cooling rate. They indicate temperatures for phase transformations like austenite to pearlite or martensite.
(1) The document analyzes a steel bar that cracked during a bending test. (2) Microstructural examination revealed a martensitic surface zone with higher hardness than the ductile ferrite-pearlite core. (3) Chemical analysis found the steel to meet specifications. (4) The steel bar was likely overquenched during manufacturing, leading to a martensite area exceeding 30% and reduced ductility, causing cracks during bending.
Tensile testing subjects a material sample to controlled tension until failure to determine properties like ultimate tensile strength and elongation. The test uses a universal testing machine to apply tension to a standardized tensile specimen, measuring properties like modulus of elasticity, yield stress, and fracture stress. The test procedure involves securing the specimen in the machine and applying tension until failure while recording the stress-strain curve.

The document discusses various challenges and considerations for welding dissimilar metals. It notes that dissimilar metals often have different physical, chemical, and metallurgical properties, requiring compromise when welding. Key factors discussed include weld metal composition and properties, dilution rates, differences in melting temperatures, thermal expansion, and heat treatments between base metals. The document provides examples of dissimilar metal welds that failed, including a superheater tube weld that cracked due to carbon migration and increased hardness. It emphasizes the importance of selecting suitable welding processes, filler metals, joint designs, preheat/post-weld heat treatments to successfully join dissimilar metals.
The document discusses various heat treatment processes. It defines heat treatment as operations involving heating and cooling of metals/alloys in their solid state to obtain desirable properties. It describes the stages of heat treatment as heating, soaking, and cooling. It then discusses various heat treatment processes like annealing, normalizing, hardening, and tempering in detail including their purposes, methods, and effects on material properties.
This chapter provides an introduction to mechanical metallurgy, including the behavior of metals under stress and strain. It discusses key concepts such as elastic and plastic deformation, ductile versus brittle behavior, and the types of failures that can occur in metals. The objectives are to describe the stress-strain response of metals and the defect mechanisms that lead to flow and fracture. Factors influencing failure like temperature, loading conditions, and material properties are also addressed.
There are several mechanisms that can strengthen materials by hindering the movement of dislocations:
1) Grain size reduction - Smaller grain sizes provide more barriers to dislocation movement at grain boundaries. According to the Hall-Petch relationship, smaller grain diameters yield higher yield strengths.
2) Solid solution strengthening - Impurity atoms distort the crystal lattice and generate stress fields that impede dislocation motion. The effectiveness depends on size difference and concentration of solute atoms.
3) Strain hardening - Plastic deformation increases dislocation density within a material, making further dislocation movement more difficult through interactions between dislocations. This causes strain hardened metals to strengthen with increasing plastic deformation.
This document discusses fracture mechanics and provides background information on the topic. It introduces key concepts in fracture mechanics including stress intensity factor, linear elastic fracture mechanics (LEFM), ductile to brittle transition, and fracture toughness. Applications of fracture mechanics are described such as its use in analyzing cracking in pavement systems. The document also covers probabilistic fracture of brittle materials and how their strength is affected by the presence of flaws.
This document summarizes Griffith and Irwin fracture mechanics theories. [1] Griffith's theory explains brittle fracture and proposes that crack growth occurs when the potential energy released by fracturing exceeds the new surface energy. [2] Irwin modified Griffith's theory for ductile materials by including a term for the energy dissipated by plastic deformation near the crack tip. Irwin's theory partitions the energy into stored elastic energy driving fracture and dissipated energy resisting it. Crack growth occurs when the stored energy exceeds the dissipated energy.

(1) Thermo-mechanical controlled processing (TMCP) is a technique that uses controlled rolling and cooling to achieve a fine, uniform microstructure with fine grains.
(2) TMCP produces steels with higher strength and better toughness than conventional steels through grain refinement down to the sub-micron level. The aim of TMCP is to replace the ferrite-pearlite banded structure with a finer microstructure.
(3) Ultrafine grain steels produced through additional heavy deformation and strain-induced phenomena have the potential for further increasing strength, toughness, and other properties but present challenges like reduced ductility that require further research.
Welding causes distortion due to differential heating and cooling rates during the process. When heat is applied to part of a structure, it expands locally. If the structure is restrained from expanding uniformly, compressive and tensile stresses develop which can result in distortion. Three factors influence distortion: 1) temperature gradients between regions of the structure, 2) restraint from thermal expansion, and 3) yield strength and modulus of the material at welding temperatures. Distortion can be controlled by techniques such as pre-setting parts, clamping during welding, and post-weld heat treatment.
This document provides an overview of fatigue in metals. It discusses stress cycles and the S-N curve used to represent fatigue data. The effects of mean stress, stress range, and stress concentration on fatigue properties are examined. Low cycle fatigue involving high strains is also covered. The document introduces approaches for assessing fatigue properties, including the cyclic stress-strain curve and fatigue crack growth resistance. Factors that influence fatigue such as temperature are also discussed.
The document discusses various heat treatment processes used to alter the properties of metals and alloys. It describes processes like normalizing, annealing, hardening, and tempering. Normalizing involves heating above the critical temperature and air cooling to refine grains. Annealing fully softens metals by heating above the critical temperature and slow cooling. Hardening involves heating above the critical temperature and quenching in water or oil to form martensite. Tempering reduces the brittleness of hardened steel by reheating below the critical temperature.
This document discusses metallurgy and material science, specifically focusing on the iron-carbon phase diagram and the microstructures and transformations associated with steels. It describes the five individual phases in the Fe-C diagram, including ferrite, austenite, cementite, and liquid. It also discusses the three invariant reactions of peritectic, eutectic, and eutectoid. The document classifies different types of steels and cast irons based on their carbon content and describes the microstructures of hypoeutectoid, eutectoid, and hypereutectoid steels. It also discusses phase transformations in steels including pearlite, bainite, and martensite
Case hardening or surface hardening involves hardening just the surface of a metal part to create a thin hardened outer "case" while leaving the inner core soft. There are several methods for case hardening, including direct hardening using austenitizing and quenching, as well as diffusion hardening techniques like carburizing (adding carbon via heating in a carbon-rich environment), nitriding (diffusing nitrogen into the surface at high heat), and cyaniding (dipping in a heated cyanide bath). Carburizing, the most common diffusion method, involves packing parts in charcoal and heating to diffuse carbon atoms into the surface before quenching.
Heat treatment is used to alter the physical and mechanical properties of metals through controlled heating and cooling without changing the shape. It involves phase transformations during heating and cooling to modify the microstructure. Common heat treatments include annealing, which involves slowly cooling a heated metal to reduce hardness and increase ductility after cold working, and normalizing, which heats metal to above the critical temperature to dissolve carbides before air cooling. Recrystallization is an important annealing process where new strain-free grains nucleate and grow to replace the deformed microstructure.
The shape of the weld pool and surrounding HAZ depends on welding parameters like welding speed and heat input. At low speeds, the shape is roughly circular in plan view and hemispherical in 3D. As speed increases, the shape becomes elongated and elliptical. At some critical speed, a tear drop shape forms with a tail. Further speed increases elongate the teardrop and can cause the tail to detach, separating the molten region into isolated parts. The shape transition is influenced by the material's thermal properties as well.
Induction hardening is an efficient surface hardening process that uses electromagnetic induction to generate eddy currents and rapidly heat metal components. It produces a martensitic microstructure upon quenching that increases hardness, strength, and wear resistance while minimizing distortion compared to traditional furnace treatments. Induction hardening takes less than a minute, whereas nitriding and carburizing can take hours, and it induces higher compressive residual stresses in the surface.
The document discusses the Jominy end quench test, which is used to measure the hardenability of steels. In the test, a cylindrical steel sample is uniformly heated, then quenched at one end with water to rapidly cool it. Hardness measurements are then taken at intervals along the sample's length from the quenched end. The results show decreasing hardness further from the quenched end, indicating how deep within the material the heat treatment can harden it. Alloying elements like chromium, molybdenum, and manganese can shift the hardness "nose" deeper, improving hardenability by slowing the transformation of austenite. The test provides critical information for selecting ste

NFL Nangal was the first key industry set up by the Government of India utilizing surplus power from the Bhakhra Dam project. It established a fertilizer plant in Nangal in 1961 which initially produced ammonium nitrate and heavy water. The plant later added urea production in 1978 and replaced its electrolysis plant with a new front-end plant in 1990. In-situ metallographic testing is carried out to examine the microstructure of components and determine degradation or abnormalities from operational conditions, using a portable kit.
This document discusses types of metallurgy, including ferrous and non-ferrous metallurgy. It focuses on describing the history and processes of ferrous metallurgy, which involves iron. Key points include that the earliest iron artifacts date back to 4000 BC in Egypt and were made from meteoritic iron-nickel. Iron smelting, which is more difficult than other metals, emerged in the Middle East around the 3rd millennium BC. The Iron Age began at different times in different places as the technology spread, starting around 500 BC in Central Europe and India/China between 1200-500 BC. Non-ferrous metals like copper are also recycled due to their extensive use.
Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their intermetallic compounds, and their mixtures, which are called alloys. Metallurgy is also the technology of metals: the way in which science is applied to the production of metals, and the engineering of metal components for use in products for consumers and manufacturers. The production of metals involves the processing of ores to extract the metal they contain, and the mixture of metals, sometimes with other elements, to produce alloys. Metallurgy is distinguished from the craft of metalworking, although metalworking relies on metallurgy, as medicine relies on medical science, for technical advancement.
Metallurgy is subdivided into ferrous metallurgy (sometimes also known as black metallurgy) and non-ferrous metallurgy or colored metallurgy. Ferrous metallurgy involves processes and alloys based on iron while non-ferrous metallurgy involves processes and alloys based on other metals. The production of ferrous metals accounts for 95 percent of world metal production.
Metallurgy is the process of extracting metals from ores and purifying them. It involves various physical and chemical steps. Key physical steps include crushing ores, concentrating them using processes like magnetic separation or flotation, and mechanically separating gangue from ores. Chemical steps include roasting or calcination to remove impurities, reduction of metal oxides using coke or other reducing agents, and electrolytic refining to obtain pure metals. The overall metallurgy process allows extraction of metals from ores on a commercial scale.
The document discusses various materials used in industrial design and manufacturing including composites, metals, ceramics, polymers, and their properties. Composites combine materials for desired properties like strength and weight. Aluminum and fiber-reinforced polymers are increasingly used in place of steel for car bodies due to their lighter weight. Ceramics can withstand high temperatures and acids but are brittle. Metals, ceramics, and polymers each have distinct strengths and weaknesses for different applications. Fatigue and creep are material failure modes that must be considered.
Metallurgy is the study of physical and chemical behavior of metals and their alloys. The earliest evidence of metallurgy dates back 5000 years to ancient civilizations like ancient Egypt and Mesopotamia. Throughout history, metallurgy advanced with innovations like extracting copper and tin to make bronze around 3500 BC, and iron around 1200 BC. Metals are extracted from ores through processes like mining, crushing, concentration, and smelting, and shaped using techniques like casting, forging, rolling, and machining. The properties of metals can be modified through heat treatments and alloying with other elements.
