The main emphasis of this study has been placed on thermomechanical (TM) processing simulations of Mn-Si transformation-induced plasticity (TRIP)-aided steel using press forging. In order to rationalize the retained austenite volume fraction in multiphase structure, three TM schedules were employed at experiment where austenite different conditioning was considered. The choice of applied strain and thermal parameters had strong impact on austenite conditioning and consequently on the kinetics of isothermal ferrite and bainite transformation. The different multiphase structure characteristics were obtained after TM, with different volume fraction of retained austenite. Modification of structural characteristics consequently influenced the mechanical behaviour of TRIP steel.

V této studii je hlavní důraz kladen na simulace plasticity oceli indukované Mn-Si tvouspomocí (TRIP)při termomechanickém zpracování pomocí tlakového kování.
