摘要 | Hot -compression bonding (HCB) as an advanced technique for preparation of large -size homogenized components is widely applied. Despite the fact that interfacial healing mechanisms during HCB have been extensively investigated, the interfacial healing mechanisms in duplex superalloys still need to be clarified. This article investigates effect of deformation temperature on multiple interface ( gamma ' - gamma ' , gamma-gamma, gamma-gamma ' ) healing mechanism of dualphase superalloys. The healing mechanism of gamma-gamma interface at different temperatures involves a necklace -like distribution of discontinuous dynamic recrystallization (DDRX) grains occupying original interface. With increasing deformation temperature, the healing mechanism of gamma ' - gamma ' interface transforms from DDRX to diffusion bonding due to weakening of strain concentration. Simultaneously, as deformation temperature increases, the deformation mechanism of primary gamma ' phase transforms from shearing by stacking fault to dislocation pairs. At deformation temperature 1100 degrees C, the healing mechanism of gamma ' - gamma interface is heterogeneous epitaxial recrystallization (HERX) induced by primary gamma ' phase driven by diffusion of Cr element in dislocation pairs. However, as deformation temperature decreases, healing mechanism in gamma ' - gamma interface transforms into DDRX. Although interfacial healing mechanism is transformed at different deformation temperatures, the synergistic action of different recrystallization mechanisms ensures that mechanical properties of joints reached the same level as those of base material. |
