摘要
利用日本国立物质·材料研究所公布的T92钢高温蠕变持久性能数据,计算出了其在不同温度下的蠕变表观激活能和应力指数,在此基础上研究T92钢的蠕变变形机制,并采用MansonHaferd方法对T92钢进行了寿命评估,确定了模型中(Ta,lgta)的取值。
The creep mechanisms of T92 steel was concluded according to apparent activation energy and stress index calculated through analyzing creep rupture data of T92 steel published by NIMS.Manson-Haferd method was used to predict the creep life of T92 steel,and the value of（Ta,lgta）was also established.
