Atomic-scale grain boundary engineering to overcome hot-cracking in additively-manufactured superalloys
Paraskevas Kontis, Edouard Chauvet, Zirong Peng +9
There are still debates regarding the mechanisms that lead to hot cracking in parts build by additive manufacturing (AM) of non-weldable Ni-based superalloys. This lack of in-depth…
