| 摘要 | This article makes an investigation into the creep behavior and deformation features of FGH95 powder Ni-base superalloy by means of creep curves and microstructural observation. Results show that this superalloy exposes obvious sensibility to the applied temperature and stresses in the experimental range. Microstructure of the alloy consists of gamma' phase of various sizes and dispersed carbide particles precipitated in the wider crystal boundaries between the powder particles. During the creep, the deformation of the alloy occurs in the form of single- or double-oriented slipping inside the grains, and some of the finer carbide particles are precipitated near the slipping traces. The wide grain boundaries might be broken into the finer grains due to severe deformation. The deformation mechanism of the alloy during creep is thought to be the activation of dislocations of double-oriented slipping, including (1/2) dislocation inside the gamma matrix phase and super-dislocation inside the gamma' phase. The formation of the stacking faults and (1/3) super-Shockleys partial dislocation configuration is attributed to the decomposition of super-dislocation in the gamma' phase. |
| 其他摘要 | This article makes an investigation into the creep behavior and deformation features of FGH95 powder Ni-base superalloy by means of creep curves and microstructural observation. Results show that this superalloy exposes obvious sensibility to the ap-plied temperature and stresses in the experimental range. Microstructure of the alloy consists of γ' phase of various sizes and dispersed carbide particles precipitated in the wider crystal boundaries between the powder particles. During the creep, the de-formation of the alloy occurs in the form of single- or double-oriented slipping inside the grains, and some of the finer carbide particles are precipitated near the slipping traces. The wide grain boundaries might be broken into the finer grains due to severe deformation. The deformation mechanism of the alloy during creep is thought to be the activation of dislocations of dou-ble-oriented slipping, including (1/2) dislocation inside the "/matrix phase and super-dislocation inside the γ' phase. The formation of the stacking faults and (1/3) super-Shockleys partial dislocation configuration is attributed to the de-composition of super-dislocation in the γ' phase. |
