Curricular information is subject to change.

The module covers the thermodynamic background to phase diagrams, which are of key importance in understanding the industrial processing of materials. In addition, the kinetics of phase transformations - which control the transformation rate (e.g. in alloy solidification) - are investigated and quantified. The topics involved are listed below.

Thermodynamic definitions. Equilibrium state of a material. First law of thermodynamics. Standard thermodynamic properties. Second law of thermodynamics. Metallurgical thermodynamics. Single component systems. Binary solutions; statistical thermodynamics and configurational entropy. Equilibrium in heterogeneous systems. Binary phase diagrams; eutectic, peritectic, eutectoid, peritectoid. Introduction to ternary phase diagrams. Examples of phase transformations in materials; experimental studies. Computer-aided calculation of phase diagrams. Kinetics of nucleation and growth. Development of microstructure.

###### Learning Outcomes:

On successful completion of this course the student will be able to:

Create the link between the phases present in an alloy and the variation with temperature and composition of the governing thermodynamic variables.
Predict the direction in which a chemical reaction, or phase change, will proceed during materials processing.
Devise a phase diagram from knowledge of fundamental thermodynamic data on materials.
Calculate the amount and composition of each phase expected at a particular temperature.
Read and interrogate ternary phase diagrams. Find the rate at which phase transformations occur.
Make the link between thermodynamics, kinetics, and microstructure.
