| 摘要 | The microstructure and tensile creep behaviors of NiAl-28Cr-5.8Mo-0.2Hf alloy were studied at 982-1100 degreesC under the applied stress of 50 124 MPa. The alloy is composed of NiAl phase, Cr(Mo) phase and Hf-rich phase. The obtained creep curves have similar shape: a short primary creep and long accelerated creep stages. The post-creep microstructure is almost the same as the original microstructure. The dominant creep deformation mechanism is controlled by the climb of dislocations. The increase of creep rate at beginning of the accelerated creep stage is related to the nucleation and propagation of creep cracks. |
