Clayton Second semester 2008 (Day)
This unit follows the microstructure development from liquid to solid state. It also addresses the thermodynamics and kinetics of liquid-solid and solid-solid transitions. The effects of heat treatment and alloying elements on the microstructural evolution are examined using steels and Al alloys as examples. The concept of transformation-Time-Temperature (TTT) diagrams as a means of description of the progress of an isothermal phase transformations is introduced. Application of Continuous Cooling Transformation (CCT) diagrams for phase transformations taken place during practical heat treatments is discussed.
On completing this unit students will understand the evolution of microstructure during solidification of alloys under equilibrium and non-equilibrium conditions, the effects of processing parameters, and how microstructures determine material properties. Students will also develop skills in laboratory practice and techniques.
