| 英文摘要 | The failure location of the 600 degrees C tensile specimens of EBW weldment of Ti-60 alloy was found to be in the base metal (BM) region, which was attributed to the superior anti-deformabilities of fusion zone (FZ) and heat-affected zone (HAZ) during tensile testing. The creep rupture property at 600 degrees C was found to be related to the level of creep stress applied: the fracture location shifted from FZ to BM region when the applied stress reached 550 MPa, at or above which the deformation mechanism changed from dislocation climbing to dislocation slipping. Fatigue cracks at 600 degrees C fatigue test were found to initiate at the surface or sub-surface of the specimen at BM region, TEM observation revealed that the deformation in BM region is mainly caused by dislocation gliding through a-phase laths, while the deformation in FZ is caused by dislocation climbing and limited dislocation slipping within the laths. |
