ABSTRACT
The influence of the substitution of Si by Al on the properties of hot rolled C-Mn-Si TRIP steel was investigated by TMCP. The results have shown that the microstructures of the present steels consist of polygonal ferrite, granular bainite and retained austenite. The Al substitution of Si in a conventional C-Mn-Si TRIP steel leads to excellent mechanical properties (UTS>714MPa, A50>31%). TMCP led to the stability of the remaining austenite and a satisfactory TRIP effect. Excellent mechanical properties were obtained through TMCP for the hot rolled TRIP steel.
