Microstructure evolution of directionally solidified DZ125 superalloy with melt superheating treatment

In this paper, the melt superheating treatment is carried out for DZ125 superalloy during directional solidification. With appropriate superheating treatment regulation, the thermal gradient and solidification velocity remain constant for different melt superheating temperatures in order to accurate...
