英文摘要：

In this article, SiCp/Copper-composites are prepared by in situ synthesis with mechanical alloying and SPS sintering. Property test and analysis of samples prepared under different processing parameters are carried out using micro hardness tester, optical microscope, X-ray diffraction. Orthogonal experiment method is adopted in studying effects of some milling parameters such as ball material ratio, ball milling speed, ball milling time and control agent on microstructures and properties of the composites. Results indicate that these parameters may play significant influences in hardness, wear resistance and relative density of the composites. Final analyses indicate that the optimized processing parameters： ball milling time is 3h, velocity of milling is 1000 r/min, control agent is 1% stearic acid, and ball material ratio is 7： 1.
