【Abstract】 The effects of rare earth on TTT curve,Ms point and phase transformation critical points of 30CrMnSi cast steel were investigated.The research results are that the starting transition curve moves rightly and the finished transition curve moves leftly,while the phase transformation critical points delays and the Ms point raises.更多还原
