研究了激光焊接Ti6Al4V合金的显微组织特征和力学性能。激光焊接后热影响区和熔合区组织特征发生明显变化，受焊接条件的影响较大。焊缝的力学性能明显取决于微观组织特征，热影响区和熔合区的强化主要是由于马氏体的形成。
The microstructural characteristics and mechanical properties in laser beam welds of Ti6Al4V alloy were investigated. The microstructural characteristics in the heat affected zone and fusion zone change obviously after laser beam welding, which are strongly influenced by the welding conditions. The mechanical properties of the welds are evidently dependent on the microstructural characteristics, and the strengthening in the heat affected zone and fusion zone is mainly attributed to the formation of martensite.
