摘　　要：利用带小孔的恒定高压发生装置，通过高压拉伸、压缩及模锻试验，研究了SiC_p/AlMMC在高等静压下的性能及其随压力变化的规律。研究表明，SiC_p／AIMMC在室温高等静压下可进行大变形，得到质量优良的零件，认为高压变形是难变形MMC成形的有效途径之一。In this paper, performance of SiC_p/Al MMC under high hydrostatic pressure (HHP) is studiedthrough tension, compression and die forming test, by means of HHP generating facilities with aperture. The re-sults show that SiCp/Al MMC can be sustained a large amount of deformation under HHP at room temperature,which enable to produce of forging with high quality. De formation under HHP is an effective method for forming ofdifficult deformed MMC.
