Crack inhibition and crystallographic texture control in an additively manufactured IN738LC Ni-based superalloy

The additive manufacturing of directionally solidified Ni-based superalloys remains a significant challenge due to the formation of stray equiaxed grains and their high susceptibility to cracking, particularly for high-volume γ´-type Ni-based superalloys. In this study, a novel strategy based on tem...
