홈페이지논문 초록 (Abstract)
For the first time, additive manufacturing was used to obtain a strong joint (bonding strength >200MPa) between stainless steel and Ti-6Al-4V using a V interlayer. The V interlayer applied via solid-state joining prevented the formation of brittle intermetallic phases more effectively than a V interlayer deposited by a liquid-state process. The microstructure and strength of the joint interface depended on the laser power and scan speed. The joint strength decreased with increasing annealing time, especially after 4 and 24h, demonstrating the presence of the Fe-V-Cr sigma-phase.[GRAPHICS]IMPACT STATEMENT For the first time, an additive manufacturing process using a V interlayer successfully produced a hybrid structure of stainless steel and Ti-6Al-4V alloy.
