Overview:

This module presents students with the major theoretical concepts associated with materials science, such as bonding, atomic and molecular structure, phase equilibria, crystallography, and dislocation theory, so that a strong understanding of the relationship between structure and properties in materials can be developed. It also introduces and presents the basic theory associated with the mechanical behaviour of engineering materials when under load, both in the elastic and plastic regimes, as appropriate to the material.

The module also presents the materials science theory within a real-world context, with a particular emphasis on the manufacturing methods that are employed to turn basic materials into components and products. Through this study it will hopefully become apparent that the properties of materials are strongly determined by the structure of materials (on levels ranging from the nano to the macro scale) and that such structure is, in turn, itself strongly influenced by the manufacturing methods utilized. It is through manufacturing methodology that engineers have the greatest ability to alter and optimise materials properties such as strength and toughness, stiffness and even corrosion resistance.
