ENGINEERING TRIPOS PART IB - 2012/2013
PAPER 3 - MATERIALS
Materials: Microstructure, Processing & Design
Leaders: Dr G.J. McShane, Dr. H. R. Shercliff, Prof. J. Woodhouse
Timing: Weeks 1-8 Michaelmas term
Structure: 16 lectures, 2 lectures/week
The aims of the course are to:
- Build on the Part IA Materials course to extend understanding of the relationships between processing, microstructure and properties.
- Describe the thermodynamic and kinetic principles governing microstructural evolution in materials, and to model the evolution of microstructure and properties.
- Develop understanding and modelling of deformation responses of materials.
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 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 general principles in interpreting phase diagrams and the theory of phase transformations.
- Apply these thermodynamic and kinetic principles and models to: (i) materials processing (e.g. solidification, precipitation, recrystallisation in metals; crystallisation in polymers; doping of semiconductors), and (ii) biological material behaviour (e.g. osmosis).
- Understand the analogy between mass diffusion and thermal diffusion.
- Describe the mechanisms of temperature-dependent creep in metals.
- Understand and model the deformation response of a range of engineering materials, including viscoelasticity, creep, and metal forming processes.
