研究了一种镍基单晶高温合金在高温（高于980℃）蠕变时的稳态蠕变行为与相应显微组织的关系。结果表明：筏形组织是稳态蠕变变形的重要特征，较短的初始蠕变阶段和较高的界面位错网密度有利于稳态蠕变变形。
The relationships between steady-state creep behavior and corresponding microstructure characterization of a new nickel-base single crystal superalloy under high temperature （〉 980℃） creep conditions were studied. The results show that rafting microstructure was the main characterization of steady-state creep stage; shorter primary creep stage and higher dislocation network density were of benefit to the steady-state creep deformation.
