英文摘要	Microstructural evolution and mechanical properties of the election beam weldments of different thickness Ti60 titanium alloy plates were investigated Metallographic examination of as-welded Ti60 electron beam welds show that there are three zones in the EBW weldments, the fusion zone (FZ), heat affected zone (HAZ), and base metal (BM). The fusion zone is consisted of columnar grains. Effect of plate thickness on the microstructure of columnar grains is small. So the microstructure of columnar grains in plate with different thickness was similar and consisted of fine alpha plates and a small amount of beta phase. The micro-hardness of welded joint was "saddle shaped" distribution, and the micro-hardness of FZ is the highest. The failure location of the room temperature tensile specimens of EBW weldment is found to be in the BM region, so the tensile strength of FZ is stronger than BM.
