Offered
Clayton First semester 2008 (Day)
Synopsis
Bonding: atomic/molecular arrangement. Crystal systems: directions & planes, stereographic projection; metallic, ionic & ceramic crystals. Defects; vacancies & interstitials; dislocations; stacking faults, twin & grain boundaries. Thermodynamics: condensed systems; entropy, Gibbs free energy; ideal &non-ideal solutions; surface energy & microstructure. Phase Equilibria and Microstructures: Gibbs phase rule; free energy diagrams; phase diagrams; deviations from ideality, phase separation; ordering; eutectic, eutectoid, peritectic and peritectoid reactions; non-equilibrium microstructures, implications for physical properties.
Objectives
On completion of this unit students will be able to: identify the different materials from which everyday products are made; understand the role of the different materials in the operation of that product; appreciate how the component would have been fabricated; understand the origins of mechanical properties of materials at the macroscopic (continuum) and microscopic (atomic) levels; appreciate the importance of a co-operative team effort in materials evaluation; and prepare written reports on laboratory experiments.
