Abstract
Titanium and its alloys have excellent combination of properties, such as low density, high specific strength and corrosion resistance, and they are extensively used in many industrial fields. This work is aiming at investigation on the microstructure and mechanical properties of Ti–6Al–3Nb–2Zr–1Mo (Ti6321) alloy joints by Electron beam welding (EBW). The results show that the microstructure of the weld metal (WM) is composed of a mixture of acicular α, acicular α′, and β. The heat affected zone (HAZ) near WM consists of acicular α, primary α, acicular β phase and lots of acicular martensite α′. The HAZ near base metal consists of primary α phase and transformed β containing acicular α. The micro-hardness of the weld metal and heat affected zone are higher than that of base metal, and there are the peak values for the HAZ near the weld metal. The tensile strength of joint is equal to that of base metal, and the fracture locations of all the tensile specimens are in base metal, and it is well in accordance with the relationship between microstructure and mechanical properties of welded joints.
