| 摘 要： | 针对单晶材料涡轮叶片的蠕变计算分析的需要,对我国自行设计的单晶材料DD3进行蠕变试验,根据试验结果提出了进行曲线拟合的方法,并与有限元法计算相结合,对拟合出的蠕变律常数进行了修正,提出了较好符合试验曲线的较精确的Norton蠕变律有关常数A、n和p值,满足了单晶叶片非线性有限元蠕变分析的要求.

| Abstract: | The creep test of DD3 single crystal material which is made in China is carried out in order to meet the needs of creep calculation and analysis of the turbine blade made of DD3,and giving out the method of fitting creep curves according to the test's results.The creep constants,that are more exact and accord with the test curves, A,n and p of Norton formula are obtained by fitting the test creep curves and modified by finite element analysis of blade of single crystal. |
