Transformation induced plasticity (TRIP) steels have a vast application in automotive industry because of theirhigh strength, high ductility and hence excellent energy absorption capacity. These characteristics of TRIPsteels are due to the existence of retained austenite in their microstructures in the ambient temperature, whichtransforms to the martensite phase during deforma...

Three low-carbon bainitic steels were designed to investigate the effects of Cr and Al addition on bainitic transformation, microstructures, and properties by metallographic method and dilatometry. The results show that compared with the base steel without Cr and Al addition, only Cr addition is effective for improving the strength of low-carbon bainitic steel by increasing the amount of bainit...

The bainitic transformation kinetics and carbon enrichment of austenite during isothermal holding at 723–923 K were investigated for an Fe-0.1mass%C-0.5mass%Si-2.0mass%Mn alloy. progressed rapidly until approximately 50 s, after which stasis was observed 823 K. concentration increased as the proceeded, showed almost constant value stasis. It reached 0.45-0.50% K, corresponds to T0’ composition ...

Carbide-free bainitic (CFB) steels with a matrix of ferrite and thin layers retained austenite, to reduce the manufacturing costs, usually do not contain alloying elements. However, few reports were presented regarding effect elements on properties these steels. Thus, this study evaluates effects vanadium rare earth (Ce-La) microalloying structure, phase transformation kinetics, mechanical carb...
