Course Content / Syllabus

The theoretical section of the course, introduces the student to: The nature of the chemical bond, and the role it has in determining the properties of the materials. The crystal structure of metals and various forms of dislocations (lattice perturbations). The process of metal solidification as well as the microstructures of metallic materials, their mechanical properties and standard methods used for testing them. Binary equilibrium phase diagrams, including analysis of the iron-carbon binary system. Various methods of mechanical, thermal and surface treatment of metallic materials. Classification and applications of various types of steel, cast-iron, copper and aluminum alloys. The problem of corrosion and several methods of protecting metallic materials exposed to corrosion conditions. Non-metallic materials, such as polymers and wood, in relation to their classification, structure, physical and mechanical properties, processing and applications.
In the experimental section of the course, laboratory experiments are performed including: Metallographic examination of metals and alloys. Determination of the hardness of metallic materials. Tensile strength testing. Cold rolling of aluminum. Thermal treatment of metals (e.g. tempering, recrystallisation and quenching) Corrosion of metallic materials. Identification and morphing of polymers. Processing glass reinforced polymers (GRP’s). Application and properties of polyurethanes.
Several methods used for testing the mechanical properties of the materials are presented.
