镍基单晶高温合金在980 ℃以上稳态蠕变行为及相应的显微组织
Steady-State Creep Behaviors and Corresponding Microstructures of New Nickel-Base Single Crystal Superalloy at Tempeoatures above 980 ℃
摘 要
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。

Abstract
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.
