One of the reasons for the versatility of steel is the ability to change the properties by heat treatment. This course covers the theory of heat treatment including the kinetic principles of solid state transformations. The influence of time on phase transformation is investigated. The interpretation of IT and CT diagrams to predict transformations and resulting microstructures is covered. Hardenability of steel is studied including factors influencing hardenability and the use of hardenability curves in the selection of steels for given applications. The effect of thermal gradients and phase transformations on distortion and residual stress in heat treated products is studied. In the labs students will perform heat treatments and analyze the resulting microstructural and property changes.
