    The goal Students will acquire knowledge on changes of microstructure during thermomechanical processing and its influence on mechanical properties, which is basis for understanding the relationship between chemical composition, thermomechanical processing, structure and properties in metallic materials. Physical basis of fracture and ddifferent fracture mechanisms are aslo explained..
    The outcomeKnowledge on mechanisms that lead to changes in microstructure and determines final properties. This subject is fundamental knowwledge for all metal forming and thermomechanical processes technolgies.
    Contents of lecturesPrinciples of crystallography. Bravais laattice, Millers indices, Weiss zone rule, Stereographic projection. Defects in crystal lattice: point, line, plane defects. Dislocation theory. Types of dislocations, geometry, Burgers vector, Stresses and energy, line tension, Dislocation sources, movement of dislocations, Unit and partial deislocations, Plastic deformation, mechanisms and geometry od slip and twinning.
