Orientation controlling of Ni-based single-crystal superalloy by a novel method: grain selection assisted by un-melted reused seed
A new grain selection method assisted by un-melted short seed was proposed to control the primary and secondary orientations of Ni-based single-crystal superalloy. The results showed that the use of short seeds could effectively avoid the formation of the melt back mush zone. Although a few stray gr...
