Interface formation and deformation behaviors of an additively manufactured nickel-aluminum-bronze/15-5 PH multimaterial via laser-powder directed energy deposition

Boyuan Li et al.

Summary: Additive manufacturing of a nickel-aluminum-bronze (NAB)/15-5 PH multimaterial by laser-powder directed energy deposition (LP-DED) achieved excellent mechanical performance and high corrosion resistance. The formation of interface characteristics was attributed to a synthetic effect of liquid phase separation, Marangoni convection, and atom diffusion.

Additive manufacturing of copper-stainless steel hybrid components using laser-aided directed energy deposition

Xinchang Zhang et al.

Summary: This study fabricates well-bonded copper-SS316 L hybrid parts using a laser-aided directed energy deposition (DED) process, with a nickel-based alloy Deloro 22 introduced between copper and SS316 L to address direct joining challenges. Tensile testing shows excellent bonding at the interfaces, with fracture occurring at pure copper and SS316 L regions. The thermophysical properties testing indicates a significant increase in thermal diffusivity and conductivity, validating enhanced thermal performance of SS316 L when joined with pure copper.
