Forming control and the relationship between microstructure and mechanical property in TIG-assisted friction stir welded joint of Ti-6Al-3Nb-2Zr-1Mo titanium alloy
In this paper, T-joints of Ti-6Al-3Nb-2Zr-1Mo titanium alloy were joined with friction stir welding, and microstructure evolution and forming mechanism were studied.The effect of using tungsten inert gas welding to heat additionally the FSW was investigated.Results show a strong effection microstructure of stir zone (SZ) due to case of whispering a
