论文名称：A study of fatigue damage evolution on pulsed Nd YAG Ti6Al4V laser welded joints

发表刊物：Engineering Fracture Mechanics

摘要：The influence of the large microstructure gradient the fatigue damage behaviour of laser beam welded Ti6Al4V was investigated. The experimental results showed that the damage evolution of fatigue residual strength in the LBW joint was higher than that in the base metal (BM) sample, and the fatigue crack growth resistance of the fusion zone (FZ) in the LBW joint was greater than that of the BM. Compared with BM specimens, the heterogeneous micro-plastic deformation was easier to obtain in the LBW joint under fatigue load due to high large microstructure gradient, which promotes crack initiation in the LBW welded joint.
