Materials Science II - Mechanical Properties

(Prof. Dr.-Ing. Gunther Eggeler)

This series of lectures is concerned with the mechanical behaviour of materials. Particular attention is paid to the physical and microstructural basis for specific mechanical properties. Firstly, the elastic and inelastic behaviour of materials is discussed. Then the role of the one dimensional lattice defect dislocation in plasticity of metallic materials is considered. In this part of the series of lectures, fundamental dislocation reactions at both low and high temperatures are addressed. Building upon the foundation given by a sound understanding of dislocations, first hardening, then recovery and recrystallization, followed by creep and finally a number of microstructural measures to enhance strength are covered. Next, the basic elements of fracture mechanics and material fatigue are discussed. The effect of temperature on the mechanical behaviour of materials with cracks is then taken into account. Finally, an introduction is given to multi-axial states of stress and reference stress criteria are introduced and discussed from a materials science point of view. Finally the wear of materials is treated. The aim of this series of lectures is to impart the students with a microstructural understanding of deformation and damage processes in engineering materials. The classes are held on Mondays from 2.00 to 3.30 pm and Wednesdays from 1.00 to 2.30 pm.
