摘要
从应变范围区分法(SRP),应变能区分法(SEP)的有关概念出发,研究DD3单晶镍基合金拉—拉应力状态下的蠕变—疲劳性能和保持时间的影响,并对其进行了定量计算;同时,用应变能区分法的数值法(SEP—NCM)实现对拉—拉应力状态下蠕变—疲劳的寿命预测。
Creep-fatigue behaviour of a Ni-base single crystal alloy DD3 under condi-
tion of tension-tension stress was investigated from some concept about strain range parti-
tioning (SRP) and strain energy partitioning (SEP). Study of effect of hold time and its quan-
titative computation was also made. Using numerical method of SEP (SEP-NCM), creep-fa-
tigue life prediction under condition of tension-tension strees was performed.
