Microstructure evolution of DD6 during different heat treatment conditions

[001] oriented DD6 alloy was prepared by directional solidification in this experiment. γ' phase precipitation phase structure of different morphology and size was obtained by different high temperature ageing heat treatment processes. Through this experiment, the feasibility of improving high temperature performance by adjusting the heat treatment process to change the microstructure of the single crystal was explored. The as-cast DD6 is first...
