Abstract
The effects of austenitizing temperature between 860℃ and 950℃ on bainite continuous transformation kinetics for 10Ni3MnCuAl steel were investigated by dilatometric experiments.The results show that the higher the austenitizing temperature,the larger the austenite grain size(AGS) and the lower the bainite transformation start temperature(B_s) and 50% transformation temperature(B_m).Though,the bainite transformation finish temperature(B_f) remains almost unchanged.The peak of bainite transformation rate shift to lower temperature with the higher austenitizing temperature,the highest bainite transformation rate at different austenitizing temperature depends on diffusion rate and driving force,of which driving force is the main factor.
