| 摘 要： | 利用真空熔炼试制了三种不同C含量的含铝TRIP钢,采用DSC测试方法测得一系列相变点,并借助Thermo-Calc软件对试验钢进行了平衡热力学计算,得到了试验钢的平衡相图及相变点的计算值,实验值比计算值偏高。综合考虑实验值与计算值的偏差,可为Al代Si TRIP钢的成分优化及热处理工艺提供参考。

| Abstract: | Three Al containing TRIP steels with different C contents were melted by vacuum melting method,and their phase transformation temperatures were measured by DSC.Phase diagrams and phase transformation temperatures of test steels were obtained by the equilibrium thermodynamic calculation which was carried out with Thermo-Calc software.The values of experimental results were higher than the calculated ones.The comprehensive consideration to the deviation between the experimental result and calculated value could provide the reference for the component design and heat treatment of the TRIP steel with Al substituting Si. |
