Physical metallurgy

Objectives To provide the student with a thorough understanding of the characteristics and mechanisms of solid state phase transformations and to then introduce the student to the manipulation of phase transformations for gains in the properties of engineering materials.

Synopsis Precipitation in Al-based and Ni-based alloys. Nucleation, metastable phases, interface structures. Kinetics. Reversion, precipitate free zones, precipitate distributions. Microstructure control and multi-stage heat treatments. Thermal stability of precipitate systems. Particle coarsening. Martensite: principles and crystallography. Decomposition of austenite. Order/disorder transformations. Microstructural engineering of steels by heat treatment: grain size control, hardenability, TTT and CCT diagrams. Alloy steels; quenching and tempering. Modelling microstructural evolution during heat treatment of non-ferrous alloys and during thermomechanical processing.
