| Abstract | Synchronous improvement of strength and plasticity (SISP) is realized for the first time in a precipitated-phase strengthened Ni-Co based superalloy through reducing stacking fault energy (SFE). Microstructure characterizations indicate that, with lowering SFE, the dislocation slip mode transforms from wavy to planar slip, meanwhile, the twinnability is also improved. Both the planar slip mode and the increased twinnability enhance the strain-hardening capability of the superalloy, which postpones the initiation of necking. Thus, the SISP in the double-phase superalloy is achieved. |
