Effect of Thermo-Mechanical Treatment with Various Annealing Hold Conditions on Al Alloyed TRIP Steel

Popis výsledku v původním jazyce

Heat and thermo-mechanical treatment of TRIP (transformation induced plasticity) steels conventionally conta-ines an annealing hold in the temperature region of bainitic transformation to obtain microstructure suitable for utilization of TRIP effect. The hold ensures stabilization of retained austenite and formation of sufficient amount of bainite.The conditions of this hold play an important role in obtaining good combination of high strength and total elongation of TRIP steel. This article deals with the effect of temperature and duration of a bainitic hold on the final microstructure and mechanical properties of TRIP steel processed by thermo-mechanical treatm ent. The holds in the interval of 350 – 500 °C were used with hold times of 25 – 1200 s. Tensile strengths of 815-976 MP awere obtained in combination with total elongations of 27-45%. The best combinations of tensile trengths around 850 MPa with total elongations above 40% were achieved for the holds at 450 °C.
