英文摘要The microstructure of EBW joints (Electron Beam Welding) of Ti-60 alloy and its rare earth phase distribution were investigated. High-temperature rotation flexible fatigue properties of the welding joints were tested and the main influencing factors were also discussed, There is a lot of alpha' martensitil microstructure in the fusion zone at the post-welding state. And the rare earth particles of 100 similar to 200 nm dispersively distributed in the boundaries and grains. The obtained welding joints have better high-temperature rotation flexible fatigue properties. The joints without welding defects are all in parent metal. Rare earth phase particles can hinder the crack propagation.
