Time Dependent Failure Assessment Curves of 10CrMo910 and 316 Stainless Steel

School of Mechanical Engineering, East China University of Science and Technology, Shanghai, 200237, China

摘要: 对10CrMo910和316不锈钢进行了总计约1万小时的蠕变拉伸试验,得到了材料的等时应力应变曲线和时间相关失效评定曲线,并给出了长时蠕变情况下的时间相关失效评定曲线方程。

Abstract: Tensile creep tests on 10CrMo910 heat resisting steel and 316 stainless steel were carried out for 10000 hours. On the basis of the experimental results, the isochronous stress-strain curves and time- dependent failure assessment curves （TDFAC） of these two steels were given. Finally, the corresponding formulae for long-term creep state, which could be utilized in the high temperature defects assessment, were established.
