摘要

Abstract

To elucidate the evolution mechanism of the microstructure and properties of the titanium al-loy during the welding process,deposited metal was prepared by oscillating laser-MIG hybrid welding with Ti-6Al-4V and Ti-4Al-3V-1.5Zr welding wires.Titanium alloy welding metal was characterized by X-ray detection,OM,SEM and EBSD to examine defects,tissue,phase composition,grain size,and fracture morphology.The tensile testing machine,impact testing machine and Vickers hardness instru-ment were employed to evaluate the strength,impact force,and hardness of the deposited met al.The results indicate that there are no obvious pores and cracks in the oscillating laser-arc hybrid welding ti-tanium alloy.The deposited metal from Ti-6Al-4V wire consists of needle-like α phase and mesh-like β phase,with fine crystal grains averaging approximately 7.96 μm in size.The hardness(HV0.2),tensile strength,and impact absorption energy were measured at 257,1 057 MPa and 41.7 J,respectively.In contract,the deposited metal from Ti-4Al-3V-1.5Zr wire is primarily composed of lamellar α phase,with larger grains averaging 8.96 μm.And this deposited metal exhibits lower hardness and tensile strength but relatively higher impact absorption energy of 49.6 J.These differences are attributed to the melting process of oscillating laser welding,the second-phase enhancement and grain refinement in-duced by vanadium Ti-6Al-4V.
