A novel method to prevent cracking in directed energy deposition of Inconel 738 by in-situ doping Inconel 718

Directed energy deposition (DED) of Ni-based superalloys has wide applications in the fields of aviation, energy and power. However, for the non-weldable superalloys like Inconel 738, cracking frequently occurs during DED and cannot be thoroughly controlled up to now. We propose a novel method to pr...
