Materials and Processes
Overview
The purpose of this unit is to introduce students to, and develop knowledge and skills in the structure of materials at the nano, micro and macro levels, and the correlating properties of the three main classes of materials – metals, polymers and ceramics. It will introduce students to the concepts involved in designing the structure of material to achieve a predetermined set of properties. Students will demonstrate and explore, through practical laboratory experience, the structure/property relations of materials and their effect on performance, and will develop an understanding of the principles of materials selection through their appreciation of failure in materials. The unit will develop students’ awareness that many materials are derived from non-renewable sources and suffer from degradation in many forms in their application – hence bringing students to the realisation that materials and technology can effectively contribute to building an ecologically friendly and sustainable environment. The unit will also inform students of the critical roles that advances in modern materials are playing in many new technologies.

Learning outcomes
Students who successfully complete this unit will be able to:
- Describe the difference in atomic/molecular structure between the major classes of materials that give rise to differences in material properties
- Analyse material response to mechanical and physical stimuli
- Compute mechanical properties of all major classes of materials on the basis of experiment
- Analyse failure in materials thereby demonstrating an understanding of the principles of materials selection
- Apply mathematical knowledge and skills to calculate a range of physical properties of materials
- Demonstrate understanding of the role and contribution of materials and technology in building an ecologically friendly and sustainable environment
