| 摘 要： | 通过对超临界火电机组用T/P91耐热钢的蠕变数据分析,探讨了T/P91钢在600℃下不同应力范围内的蠕变机制以及服役过程中的蠕变损伤.并使用基于材料物理本质建立的CDM(continuum damage mechanics)模型来模拟高应力范围内T/P91钢的蠕变曲线,将模拟结果与文献中的实验数据进行对比,表明模拟结果是可信的.

| Abstract: | For safe use of the equipments in power plants,creep life prediction of the material served at high temperature is an important issue.With the purpose of the existing problems in overestimation of creep strengths,it is essential to analyze the creep mechanism and the creep damage to material in serving.In the present work,through analysis on creep curves of the T/P91 thermal resistant steel served in the super critical steam conditioned thermal power plants,the creep mechanism and the creep damage of T/P91 ... |
