Forming of new steel grades

Popis výsledku v původním jazyce

The transformation of austenite to martensite is fundamental to the hardening of carbon steels. This transformation plays an important role for mechanical behaviour of low-carbon ferrous alloys containing 5 to 20 vol. % retained austenite. The effect, known as transformation induced plasticity (TRIP), is manifested by unusual work hardening and high uniform elongation - properties very desirable for thin sheets applied for automobiles parts . The influence of hot deformation on microstructure of a hot-rolled Si-Mn TRIP steel was evaluated in effort to better control retained austenite content. In the study, axial compressive strain varying in amount from 0 to 60 % were imposed in the austenite phase field, and effects of on the formation of polygonalferrite, bainite and retained austenite were determined. In addition, modifications in simulated coiling temperature from 420 °C to 480 °C and cooling rates from the rolling temperature, between 10 °C.s-1 and 35 °C.s-1, were assessed.
