This module is not approved as an Elective

Objectives

The objectives of this module are to:
- understand the physical and chemical principles underlying phase transformations in materials;
- understand how phase transformations may be exploited to produce materials with specific microstructures to yield desired properties;
- understand how control over phase transformations may be exerted by an appropriate choice of processing route.

Learning outcomes
At the end of this module, students should:
- understand the thermodynamic, kinetic and morphological principles underpinning phase transformations from the vapour, liquid and solid states;
- understand how phase transformations may be controlled to produce a specific microstructure in metals, ceramics, polymers and composites;
- be able to apply these principles in understanding the design and capabilities of materials processing techniques.

Syllabus

- The importance phase transformations;
- Elements of a phase transformation;
- Thermodynamic order of a phase transformation;
- Diffusion;
- Thermodynamics: equilibrium; phase diagrams and driving forces; effect of surfaces and interfaces on equilibrium;
- Kinetics of first and second order phase transformations: diffusive and displacive transformations; nucleation; growth; transformation rate;
- Microstructural development during transformations from the vapour, liquid and solid states;
- Controlling microstructural development in materials processing through phase transformations.
