This module is not approved as a discovery module

Objectives

On completion of this module, students should:
- be familiar with the basic properties of engineering materials and be able to relate these properties to the structure and microstructure of the materials;
- understand the different modes of failure of engineering materials and relate these to service conditions, failure mechanisms and micro-structural changes;
- understand how processing and manufacturing methods can influence both the bulk and surface properties of materials;
- be able to draw on this knowledge to gain an understanding of the role and importance of materials selection within the engineering design process;
- understand the fundamentals of metal, ionic and covalent crystal structures;
- understand the relationship of crystal structure to the properties of materials;
- be able to interpret X-ray powder diffraction patterns.

Learning outcomes
1. The students will gain knowledge and understanding of the structure and properties of metals, ceramics, polymers and composites.
2. They should have developed an ability to assess materials for delivering desired properties in specific engineering applications.

Skills outcomes
On completion of this module, students will be able to understand:
- the definition of physical properties of metals, ceramics, polymers and composites
- their origin
- the structure and property relationship
- the calculation of properties from given information
- how to extend this knowledge to materials selection for specific application
- atomic packing in metal crystal structures
- basics of ionic crystal structures
- how to interpret X-ray powder diffraction patterns.

Other skills outcomes include Close Reading (Practiced and Assessed)
