Influence of temperatures on creep mechanism of a single crystal nickel-based superalloy

摘要

By means of calculating stacking fault energy (SFE) of the single crystal nickel-based superalloyat different temperatures,measuring creep properties and analyzing dislocation configuration,an investigation has been made into the influence of the stacking fault energy on the creep mechanismof the alloy at different temperatures.Results show that there is a lower stacking faultenergy (SFE) of the alloy at 760C,and SFE of the alloy increases with the temperatures.
