Introduction to the fundamentals of materials behaviour and properties

Material Selection: Property and requirement profiles, economical aspects Electronic structure of solids (reciprocal lattice, ); Energy bands (free electron gas, real metals, semiconductors, insulators, ferromagnets), Density of states Structure of materials: bonding, ideal and real structures, lattice efects, .. Relationships structure-properties Mechanical behaviour: elastic and anelastic effects; strength, plasticity/ductility; dynamic and cyclic properties; fatigue endurance strength, fundamentals of fracture mechanics, fracture toughness, threshold, da/dN curves, testing procedures, structural reliability, statistical evaluation. Modification of mechanical properties, role of defects, strengthening mechanisms, practical relevance and application (fundamentals of material treatment, hardening, thermomechanical treatment) Thermal properties: thermal conductivity and diffusivity, thermal expansion Thermoelectric effects Electrical conductivity; relevant parameters; conductors, insulators, semiconductors; superconductors Magnetism, magnetic properties, soft and hard magnets, frequency effects, anisotropy Optical behaviour: reflexivity; transmission; refraction; luminescence Attention: the lecture is held in German language!
