The document contains details of a cycle test for an engineering materials and metallurgy course. It includes two parts - Part A with 5 short answer questions worth 2 marks each, and Part B with 2 long answer questions worth 16 marks each. Part A questions ask about definitions of terms like solid solutions, eutectoid reactions, ferrite and cementite. It also asks about classification of steels based on carbon percentage and the definition of ledeburite. Part B long answer questions can involve describing the iron-iron carbide equilibrium diagram, explaining types of solid solutions or describing reactions like eutectic, eutectoid, peritectic and peritectoid with diagrams.
