Microstructure evolution and formation mechanism of a crack-free nickel-based superalloy fabricated by laser engineered net shaping
Optics & Laser Technology(2020)
摘要
•An independently developed nickel-based superalloy powder was deposited by laser engineered net shaping.•The as-deposited of a nickel-based superalloy with the crack-free structure was obtained.•The microstructure evolution and formation mechanism of the crack-free structure is proposed.
