| 英文摘要 | Microstructure, hardness, tensile and high cycle fatigue (HCF) properties of the welded dissimilar joints of Ti60 and TC17 titanium alloys had been investigated in this study. A significant microstructural change was observed to occur after welding, with rod-like alpha and beta phases in the fusion zone (FZ), equiaxed alpha phases, fine alpha laths and beta phases in the heat-affected zone (HAZ) of TC17 side and acicular martensite alpha' phases+"ghost" alpha phases in the HAZ of Ti60 side. The microhardness across the joints exhibited an inhomogeneous distribution with the highest hardness of similar to 404 HV in FZ and the lowest hardness of similar to 304 HV in base material (BM) of Ti60. All the joints tested in tension fractured at BM of Ti60 side. Fatigue limits of the joints at 10(7) cycles were 425 MPa at room temperature and 380 MPa at 400 degrees C, respectively. Welding micropores were found to be the main source of fatigue crack initiation. (C) 2018 Published by Elsevier Ltd on behalf of The editorial office of Journal of Materials Science & Technology. |
