摘要:
通过多截面试样蠕变实验方法对316L奥氏体不锈钢600 ℃蠕变行为进行研究,并基于多截面蠕变实验结果,结合复合时间硬化蠕变本构模型、反向有限元方法以及神经网络方法,建立了316L奥氏体不锈钢蠕变本构模型。该蠕变本构模型预测的蠕变曲线与标准蠕变实验方法得到的蠕变曲线吻合。多截面蠕变实验方法能够通过单根多截面蠕变实验获得多载荷下的蠕变实验结果,从而提高蠕变实验效率。
Abstract:
The creep behavior of 316L austenitic stainless steel at 600 ℃ was studied by multi-section creep test. Based on the experimental results, the creep constitutive model of 316L austenitic stainless steel was established by considering the combined time hardening creep constitutive model, the inverse finite element method and the neural network method. The creep curves predicted by the creep constitutive model agree with the ones obtained from the standard creep test method. Therefore, the multi-section creep test can obtain the creep results under multiple loads through a single specimen and get higher creep experimental efficiency.
