13. Module Synopsis

MMCH 701 Introduction to Materials Technology

Metals, ceramics, polymers and composite materials. The course will show that the behavior of materials is directly linked to their fundamental structures, and how structures and hence properties may be altered through processing. Properties, processing, design and environmental protection and degradation will be considered. Basic concepts of fracture mechanics and fatigue, with emphasis on practical applications for metals, ceramics, polymers and composites will be dealt with.

MMCH 702 Characterisation of Materials

Characterisation methods based on microscopy, chemical, physical and structural analysis and thermal techniques for materials and coatings.
