摘要 简要介绍了总应变-应变能区分法(TS-SEP)的基本假设和基本方程,应用TS-SEP法对三种金属材料(304不锈钢、1Cr-1Mo-0.25V钢和2.25Cr-1Mo钢)的热机械疲劳试验数据进行了分析和预测,初步评估了TS-SEP法对热机械疲劳数据的相关和预测能力。研究结果表明:TS-SEP法与总应变-应变范围区分法(TS-SRP),对三种金属材料的热机械疲劳试验数据具有相当的相关和预测能力,寿命预测分散带均在2倍范围内。 The basic concepts and equations of Total Strain Version of Strain Energy Partitioning （TS-SEP） are introduced briefly. Then the correlative and predictive capabilities of TS-SEP to thermomeehanical fa- tigue （TMF） data of three metals （Type 304 Stainless Steel, 1Cr-lMo-O.25V Steel and 2.25Cr-lMo Steel） in the literature are evaluated. The result indicates that TS-SEP and Total Strain Version of Strain Range Par- titioning （TS-SRP） have comparative correlative and predictive capabilities with the TMF data of three steels. The maximum life prediction scatter bands of two methods are both less than 2.0.
