To secure the required properties of highly stressed parts from the automotive industry these parts need to be heat treated, in many cases case hardened. This is traditionally performed in central hardening shops. However, the separation between machining and heat treatment involves great efforts regarding transport and buffering of parts leading to extended throughput times and therefore additional costs. The use of modern vacuum heat treatment technologies and the introduction of flexible, modular heat treatment systems allows for the integration of heat treatment into the mechanical production environment, and as of recently also directly into the process chain of part manufacturing. ]]>

Abstract This paper shows the latest progress in steel grades and in case hardening technology for gear components. To answer the demand for fuel-efficient vehicles, modern gear boxes are built much lighter. Improving fatigue resistance is a key factor to allow for the design of thin components to be used in advanced vehicle transmissions. The choice of material and the applied heat treat process are of key importance to enhance the fatigue resistance of gear components. By applying the technology of Low Pressure Carburizing (LPC) and High Pressure Gas Quenching (HPGQ), the tooth root bending strength can be significantly enhanced, compared to traditional heat treatment with atmospheric carburizing and oil quenching. Besides heat treatment, significant progress has been made over the past years on the steels being used for gear components. The hardenability of case hardening steels such as 5130H, 5120H, 20MnCr5, 27MnCr5, 18CrNiMo7-6 etc. has been stepwise increased in recent years. An important factor for fatigue resistance is the grain size after heat treatment. Therefore, grain size control is a key goal when developing new modifications of steel grades. After enhancing grain size control, it was possible to increase the carburizing temperatures over the past years from 930属C to 980属C (1700属F to 1800属F) which resulted in shorter heat treatment cycles and thus in significant cost savings. With the introduction of new microalloyed steels for grain size stability, carburizing temperatures can now be even further increased to temperatures of up to 1050属C (1920属F), leading to even more economic process cycles. By adding microelements such as Niobium or Titanium in the ppm-range, nitride and carbonitride-precipitates are formed. These precipitates effectively limit the grain-growth during the heat treatment process.]]>

by V. Heuer, T. Leist, G. Schmitt ABSTRACT: Controlling distortion is of key importance during the case hardening process for the production of automotive and non-automotive metallic components. By effective control of distortion and the variation of distortion, significant costs in post heat treatment machining processes can be avoided. In some cases it is even possible to eliminate all post-machining. In other cases it may be possible to avoid the press-quenching of individual components, resulting in huge cost-benefits. A recently introduced new vacuum furnace design allows the treatment of small batches in a single layer of parts (2D-treatment) which allows for easy automated loading and unloading of the fixture-trays. By using the small batch concept, a continuous flow of parts can be established (One Piece Flow). There is no need to wait until enough parts are collected to build a large batch with multiple layers (3D-batch). This compact furnace unit can be implemented into the heart of the production chain and provides heat-treatment processes which can be fully synchronized with the green and hard machining-operations. When performing case hardening, the components are Low Pressure Carburized (LPC) at high temperatures (1050 属C) followed by gas quenching. The treatment in single layers offers an optimum in quality regarding: temperature homogeneity, quench homogeneity and distortion control. Typical components for this technology come from the automotive, aerospace and tool industry. The directly following contribution in this Journal (A. Schuler et al., p. 90-98) shows more results achieved with this technology on selected truck-components such as gears and sliding-sleeves.]]>

When the topic of metalworking is raised, most of us think of drilling a hole in a piece of metal or bending a metal part to form a component for an automobile. Not as many individuals realize that another process included under the realm of metalworking is heat treating or quenching. Heat treatment is utilized to adjust the physical and mechanical properties of metals so that they can be used in subsequent metalworking applications. These properties are changed by the controlled heating and then cooling of metals. In many cases, the objective of heat treatment is to increase the strength of a specifi c metal alloy. Most operations are conducted on steel alloys, but nonferrous metals such as aluminum and titanium also can be heat treated.]]>

Often, the required hardness qualities of parts manufactured from steel can only be obtained through suitable heat treatment. In transmission manufacturing, the case hardening process is commonly used to produce parts with a hard and wear-resistant surface and an adequate toughness in the core. A tremendous potential for rationalization, which is only partially used, becomes available if the treatment time of the case hardening process is reduced. Low pressure carburizing (LPC) offers a reduction of treatment time in comparison to conventional gas carburizing because of the high carbon mass flow inherent to the process (Ref. 1). By increasing the carburizing temperature, a further significant increase in productivity is obtained, which is not possible in gas carburizing systems to this extent due to furnace component and process limitations (Ref. 2). By adding micro-alloy elements such as aluminium, niobium and titanium as well as properly adjusting the nitrogen content, modern case hardening steels have become sufficiently fine-grain resistant even in temperatures above 1,000属C (1,830属F) (Ref. 3). Todays vacuum carburizing systems are suited for heat treatment in temperature above 1,000属C.]]>

Integrating heat treatment into the manufacturing line has been a topic of discussion for many years. Todays production philosophy for gear components usually relies on the traditional separation between soft machining, heat treatment, and hard machining. Heat treatment is performed in a central hardening shop, and there is no continuous flow of production parts between the different operations such as soft machining, heat treatment, shot peening, and hard machining. Instead the parts are first collected into batches and then moved from operation to operation, so large numbers of production parts are being stored in buffers or are in transit between the different operations. A continuous flow of production parts between operations is only occurring today between some of the soft machining operations and some hard machining operations. This discontinuous flow of production results in increased logistical and documentation efforts, increased turnaround times and, ultimately, in increased production costs.]]>

Dual vacuum furnaces with separated heating and cooling processes are providing several advantages when compared to single chamber vacuum furnaces. This includes faster heating up, less energy consumption, more quenching severity and less maintenance. Accordingly a new, second generation of dual vacuum furnace for low pressure carburizing and high pressure gas quenching, DualTherm速, was developed using proven technologies from the ModulTherm速 series of vacuum furnace systems. The first furnace was recently installed at a commercial heat treater and is now in three-shift-operation.]]>
