Course objectives:
The purpose of the Materials Engineering course is to enable students to understand the internal structure of metallic materials how this influences it’s most important properties, and the methods that we can use to influence these properties to set the most appropriate values for use, and to make material selections for engineering parts.

Course content - lectures:

Introduction: materials, their structures and properties. Mechanical testing: tensile testing of metals. Hardness testing of materials (Brinell, Vickers and Rockwell). Impact testing. Fatigue. Crystal structures of metals. Lattice imperfections. Iron – carbon alloy system. Equilibrium and non-equilibrium microstructure. Determination of phases and microstructures. Microscopy. Structural steels. Tool steels, steels for special applications. Cast irons. Nonferrous metals. The effect of cold forming on mechanical properties of metals. Heat treatment technologies. Effect of heat treatment on steel properties. Ceramics. Production of ceramic materials, properties and field of application. Materials selection: case studies.
