Timing and Structure
Weeks 1-8 Michaelmas term. 16 lectures, 2 lectures/week
Aims
The aims of the course are to:
- Build on the Part IA Materials course to extend understanding of:
- (i) the fundamental thermodynamic and kinetic principles that govern the microstructure and properties of materials;
- (ii) the practical materials processing techniques that employ these principles to manipulate microstructure and properties for engineering applications;
- (iii) strategies for modelling the deformation and failure of materials.
Objectives
As specific objectives, by the end of the course students should be able to:
- Understand the importance of temperature, composition and deformation in controlling the evolution of material microstructure and properties.
- Understand the general principles in interpreting phase diagrams and the theory of phase transformations.
- Understand and describe the concept of the thermodynamic driving force for microstructural change.
- Understand how diffusion occurs, and derive and apply mathematical models of one-dimensional diffusion.
- Understand the analogy between mass diffusion and thermal diffusion.
- Apply thermodynamic and kinetic principles to predict a range of material behaviour, including rubber elasticity, oxidation and corrosion.
- Apply these thermodynamic and kinetic principles to practical materials processing (e.g. solidification and casting; precipitation in metals; crystallisation in polymers; doping of semiconductors).
- Understand and model the deformation response of a range of engineering materials, including temperature-dependent creep and metal forming processes.
- Understand and model the stress-state dependence of failure for a range of engineering materials.
