摘要 论述了零件在持久高温工作条件下的蠕变机理,提出了建立蠕变函数的3种假设,通过对等时蠕变曲线和时间函数的研究,得出蠕变方程和松弛方程,进而作出蠕变曲线和松弛曲线,并指出大量实验的数据与理论研究结果的一致性. This paper treats creep mechanism of component under lasting hot work,it gives three hypothesisestablishing creep function.The equation of creep function and relaxation are given through researching isochronalcreep curve and time function,then it drawn creep curve and relaxation curve,indicate consistency of researchresults and lot of experimental datas.
