以S31603奥氏体不锈钢材料为研究对象，开展应力控制下的高温疲劳试验，获得固溶态和经不同应变强化量预处理的S31603奥氏体不锈钢高温疲劳寿命试验数据。基于Hull-Rimmer空洞长大理论，建立适用于应力控制下的材料疲劳寿命预测模型，并对固溶态和应变强化态S31603奥氏体不锈钢进行寿命预测，预测结果与试验值吻合较好。在此基础上，结合不同应变强化量下材料的疲劳寿命变化趋势，进一步建立耦合应变强化预处理量的材料疲劳寿命预测模型。与实测寿命相比，预测寿命位于±1.5倍误差带之内，预测效果良好。建立的高温应力控制下的材料疲劳寿命预测模型形式简洁且具有清晰明确的物理意义，可用于应力加载下金属材料的高温疲劳寿命预测。

A fatigue experiment under stress control at high temperature is carried out for S31603 austenitic stainless steel and test data of fatigue life of solution annealed(SA) steel and cold stretched(CS) with different level steel is obtained. Based on the Hull-Rimmer cavity theory, a fatigue life prediction model applicable to stress controlling is developed. The fatigue life of the SA and CS steel is predicted by the model and the results are in good agreement with the experimental data. A model coupled with cold stretching level is deduced from two key factors：The model which applied to SA material and the changing trend of test data for the fatigue life of CS material with different level. Compared with the experimental data, the prediction results which come from the prediction model coupled with cold stretching level is found to be very satisfactory with an error band less than ±1.5 times. This model is simple in form along with clear physical significance, which is suitable for the prediction of metal material under stress control at high temperature.
