MECH 221 - Materials Science

The objective of this course is to provide students with a basic understanding into the structure, behaviour and properties of the typical, common engineering materials - metals, ceramics, polymers and composites and the methods of observing, measuring and interpreting these properties. It covers the following topics: Relationships between properties and internal structure, atomic bonding; molecular, crystalline and amorphous structures, crystalline imperfections and mechanisms of structural change. Microstructures and their development from phase diagrams. Structures and mechanical properties of polymers and ceramics. Thermal, optical, and magnetic properties of materials. Lectures: three hours per week. For more details please see the course outline.
