The analysis of hardening of metal materials: Structural level of deformation and parameters of thermomechanical treatment

There has been researched the interdependence of the process of microalloying, thermomechanical treatment and obtained mechanical characteristics of steel and AIMgSi alloys. There have been analyzed the hardening mechanisms of the mentioned alloys in correlation with grade, speed and temperature of strain. The achieved effects of alloys hardening are the consequences of combined operations of grain raffination, precipitation of dispersing particles of microalloying elements and increased density of dislocation.
