Interfacial Features of Stainless Steel/Titanium Alloy Multi-metal Fabricated by Laser Additive Manufacturing
文献摘要:
Laser additive manufacturing(LAM)is promising for fabricating multi-metallic component,but the mechanism of micro-structural evolution at the interface of two metals is still needed to research further.In this study,a 316L stainless steel/Ti6A14V alloy multi-metal was fabricated by LAM,and the mechanism of intermetallic phase transformation was deeply investigated.Results show that a strong reaction zone(SRZ)can be induced at the interface of the multi-metal.The phase constituents at the SRZ vary from x(Ti5Fe17Cr5)+Fe2Ti+α'-Ti+p-Ti or FeTi to Fe2Ti+x when the laser power is increased.When the scanning speed is further decreased,the thickness of the SRZ is significantly increased,and α'-Ti phase is also formed at this region besides Fe2Ti and x phases.Moreover,the micro-hardness at the SRZ is increased,caused by the intermetallic phase transformation and elemental interdiffusion at the interface.
