Course Objective

1.Design a simple thermal analysis tests by use of thermocouples and construct a phase diagram of a binary system, find the composition of an unknown alloy composition by using eutectic and liquidus temperatures. 2.Explain basic solidification mechanisms and differentiate solidification macrostructures of pure metals and binary nonferrous alloys. 3.Explain the white and gray solidification of cast irons and eutectic modification of Al-Si alloys in terms of solidification mechanisms and solidification microstructures. 4.Describe the conditions in the production of gray, white and nodular cast irons. 5.Explain the effect of inoculation, superheat and undercooling on the micro and macrostructures and mechanical properties interpretation of the cooling curves by using DT values of the curves after and before inoculation with FeSi based inoculants. 6.Describe the conditions to control the final microstructure and mechanical properties in centrifugal casting of metal parts.
