Abstract

The A1 critical transition temperatures (Hereinafter referred to as A1) of P91 heat resistant steels (Hereinafter referred to as P91) with different alloy elements were simulated by the continuous cooling simulation method of JMat Pro (JMP) software, and the statistical analysis tool of the JMP was used to analyze the simulation results, and the effects of the content of alloy elements Cr, C, Mo, Mn, Ni, V on the A1 of P91 were studied. Obtained results indicated that the A1 of P91 decreases firstly and then increases with the increasing of the content of Cr and Mo, the content of Cr has a great effect on the A1 of P91, the effect of the content of Mo is almost negligible; when the content of Cr is 8.8wt%, the A1 of P91 has the minimum 814 ; the A1 of P91 decreases almost linearly as the content of Mn increases, when the content of Mn increases from the minimum to the maximum, the A1 of P91 is reduced by about 7 ; the A1 of P91 increases firstly and then decreases as the content of Ni increases, and when the content of Ni is 0.2 wt%, the A1 of P91 has the maximum 815 ; the A1 of P91 decreases firstly and then increases with the increasing of the content of V, it has the minimum 814 when the content of V is 0.2wt%.
