Effect of Melt Superheating Treatment on the Microstructures and Purity of a Directionally Solidified Superalloy

In this paper, the effects and the mechanisms of melt superheating treatment (MST) on a directionally solidified alloy were investigated. The mass loss rate of the superalloy becomes severe as the MST temperature rises. The chromium, tantalum, and hafnium are the primary evaporation elements during...
