| Abstract: | Based on the optimum parameters obtained from prevenient experiments, the linear friction welding (LFW) experiment of Ti -17 alloy was carried out with homemade XMH -160 LFW machine, and the changes of the friction power and interfacial temperature during the welding were examined. According to the friction power curve, the shear strength of interface metal in the joint was calculated. The evolution characteristics and correlations of friction powder, interfacial temperature and interface shear strength wer... |
