Effects of Withdrawal Rate on the Microstructure of Directionally Solidified GH4720Li Superalloys
Increasing the ingot size of GH4720Li superalloys makes it difficult to control their microstructure, and the withdrawal rate is an important factor in controlling and refining the microstructure of GH4720Li superalloys. In this study, GH4720Li superalloy samples were prepared via Bridgman-type dire...
