Physical Metallurgy

Aim

This course gives the essence of materials science and advanced surface engineering as well as the thermodynamic conditions for nanotechnology. The aim is to give an understanding and control of the structure of matter at the ultramolecular level and the relation of this structure to properties (mechanical, electrical, etc.). This includes phase transformations based on a thermodynamical description of the liquid and solid state. We study the more complex features of the behaviour of functional materials and materials in extreme states. Focus is on aspects controlled by atomic diffusion and crystal defects. The course is tangential to physical metallurgy, crystallography, and semiconductor technology, as well as continuum and atomistic mechanics of solids. A goal is also to learn about the design and processing of electronic device materials and construction materials engineering.

Content

This is a fundamental course in materials science following an international tradition. It concerns different classes of functional materials including metals, alloys, semiconductors, ceramics. It further deals with the thermodynamics of binary systems,; Phase diagrams; Equilibrium in solid solutions; Metastable states; Phase transformations; Precipitation; Kinetics for grain growth; Crystalline phases; Polytypism; Defects in crystals incl. vacancies, interstitials and dislocations; Solutions and alloys. Atomic processes: diffusion; Multiphase materials; Microstructure; Nanostructure; Relationships between theory, materials synthesis and processing, structure/bonding, and properties; Elasticity; Plasticity and Fracture; Materials Design and Processing
