Research Progress in Influence of Deviation from[001]Orientation Angle on Creep Behavior of Nickel-based Single Crystal Superalloys
The main stress direction of nickel-based single crystal superalloy blade is[001]crystallographic direction.However,the blade stress direction generally deviates from the[001]orientation at a certain angle during actual prepa-ration.The research progress on the creep behavior of nickel-based single crystal superalloys with different angles devi-ating from[001]crystallographic orientation was introduced,and the relationship between creep behavior and devia-tion from[001]crystallographic orientation was summarized.In a word,the orientation deviation angel has little influ-ence on the creep property of superalloy at high temperature,while the creep property of single crystal superalloys with small deviation from[001]orientation and close to[011]orientation is superior to that of ones close to[111]orienta-tion at medium temperature.
