Microstructures and mechanical properties of Ni60 alloy fabricated by laser metal deposition

open access: yesMaterials Research Express, 2020
Due to its low melting point and high hardness, Ni60 (Ni–Cr–B–Si) alloy is widely used as surface cladding material for mould steel. In present study, Ni60 alloy thin-walled samples were fabricated using laser metal deposition (LMD) technology on H13 ...
