Metallic alloys, be it based on iron, aluminium, magnesium or titanium matrix, owe their properties and performance to the assembly of phases and defects that we call the microstructure. Thermodynamic characteristics and kinetic processes on the nano- and micro-scale control the formation of the microstructure during thermomechanical treatments. The physical background of metallurgical processes is studied experimentally and theoretically in order to understand the relationship processing-microstructure-properties across the length scales. Main topics in this research are the development of advanced high-strength steel and aluminium alloys….
