Özet
Due to the moderate formability of high strength low alloy steels (HSLA), the steels called transformation induced plasticity (TRIP) have been developed. They are especially used in the production of automobile shock absorbers and the beam supporting parts. The microstructure of these steels consists of the distribution of ferrite, bainite and (5 - 10%) residual austenite phases. The strength and formability of steels are generally provided by bainite, ferrite and the residual austenite phases in the structure. During shaping, the residual austenite turns into martensite and gives high strength to the steel. Considering the literature studies, it is pointed out that there is a lack of information about the effect of cold treatment on TRIP steels. For this reason, in the study, cold treatment performed to the TRIP800 steel for two hours at various temperatures. Thus, the mechanical properties and microstructure of the samples were examined in detail.
