The purpose of the module is to introduce the student to the structure and properties of solid materials. The objectives are to discuss the major classes of solids and their properties and applications, and to present the physical principles needed for an understanding of the observations.

Structure & bonding: atomic structure; primary & secondary bonds, bonding forces & energies. Structures of metals, ceramics & polymers: crystal structures, Miller indices & reciprocal lattice, X-ray diffraction, non-crystalline solids, polymer molecules & configurations, thermoplastic & thermosetting polymers. Imperfections: point defects, dislocations. Diffusion: diffusion mechanisms, steady and non-steady state diffusion. Mechanical properties: elastic deformation, mechanical behaviour of metals, ceramics & polymers. Deformation & strengthening: dislocations in metals & ceramics, hardness twinning, Hall-Petch effect, deformation & strengthening of polymers. Failure: fracture & toughness, fatigue, creep, wear. Phase diagrams: Gibbs' phase rule, binary & ternary phase diagrams, interpretation of phase diagrams. Phase transformations: homogeneous & heterogeneous nucleation, growth, metastable & equilibrium states. Applications of materials: ferrous & non-ferrous alloys, glasses & ceramics, plastics & elastomers.

- Discuss the physical processes responsible for the observed properties of solids. - Define key concepts of crystallography, mechanics, thermodynamics and kinetics, and phase diagrams relevant to solid materials - Explain the importance of microstructure and its effects on properties. - Derive relevant equations describing solid materials from basic laws and principles. - Solve numerical problems from information provided on the topics covered.

Discuss the importance of the physics of solids in the application and selection of materials.

- Perform experiments requiring precise measurement. - Use mechanical, optical and electronic apparatus for observation and measurement.

Students will learn via interactive lecture, laboratory, experiential tutorial and problem based private study.
