Determination of the hot forming activation energy – methodology.
Mathematical description of the recrystallization kinetics, adjustment of Avrami equation.
Boundary state of stress, plasticity limit, state of stress indicator, maps of fracture mechanisms.
Possibilities of influencing the structure-forming processes in the course of hot forming and final cooling.
Methodology of the transformation diagrams, effect of the previous deformation on (D)CCT diagrams.
