Abstract: Based on the means of isothermal compressive experiment and metallographical microscope, rheological behavior of SiCp/2024 composites is investigated. The results show that flow stress of SiCp/2024 composites fell down quickly with increasing experimental temperature. When holding time is relatively short, compressive stress of the composites is less than unreinforced matrix alloy. SiCp/2024 composites have character of pseudoplastic fluid in semi-solid state.
