Microstructure and defects in a Ni-Cr-Al-Ti γ/γ’ model superalloy processed by laser powder bed fusion

Additive manufacturing (AM) of non-weldable high-γ’ Ni base superalloys is challenging due to various issues, but notably because of their inherent cracking propensity. Typically, the segregation of melting point-depressant elements to grain boundaries (GB) drastically increases the solidification i...
