| 摘 要： | 研究了00Cr18Ni10N钢的高温持久强度.在Larson-Miller方程基础上,利用全微分和状态函数特征,建立了00Cr18Ni10N钢在给定温度条件下持久强度与高温抗拉强度之间关系的数学模型.通过试验结果表明,利用该数学理论模型预测00Cr18Ni10N钢在700℃,持久拉伸200h理论与实测持久强度值相符,相对误差为0.6%.

| Abstract: | The high temperature rupture strength of 00Cr18Ni10N stainless steel is studied, The mathematical model of relation between the rupture strength at given temperature and the high temperature tensile strength of 00Cr18Ni10N steel is established by means of total differential and state function on the basis of Larson-Miller equation. The test data indicate： The rupture strength of 00Cr18Ni10N steel at 700℃ lasting 200 h calculated by the model conforms to the tested value. The relative error between them is 0. 6%. |
