| 中文摘要 | A NiAl-based composite with HfB2 dispersed particles has been synthesized by mechanical alloying of Ni, Al, Hf and C powders. The formation mechanism of NiAl-HfC during milling can be attributed to two chemical reactions: Ni+Al-->NiAl+DeltaH; Hf+C-->HfC+DeltaH, induced by mechanical collision in a certain period of time, which results in an abrupt exothemic reaction. Hot pressing (HP) and hot isostatic pressing (HIP) have been used to make the NiAl-10HfC compacts near fully dense. Compressive testing from room temperature to 1000degreesC indicated that the yield stress of NiAl-10HfC composite is 3similar to4 times higher than that of cast NiAl and correspond to the MA NiAl-10TiB(2) composite. In the meantime, yield strength at high temperature is dependent on strain rate, and deformation is controlled by diffusion mechanism. |
