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

Journal of Materials Research and Technology
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.
