| AlNi_x intermetallic compounds have many advantages when it is utilized for high-temperature, it is characteristic of high yield stress reciprocal of the temperature, stress ratio, good oxidation-resistance wear resistance, and high-creep resistance. Currently, a lot of manufacturing skills of direct-sintered materials by HPCS process have been developed. When the direct-sintered material is manufactured by HPCS process, the factors that affect the densfication of it are preheating temperature and pressure. Therefore the higher the preheating temperature and the pressure, the more densified the specimen. It is found that the porosity and specific wear of sample produced were decreased and grain size and micro hardness of sample were increased with increasing preheating temperature. |
