| Abstract: | The preparation process of SiCp/Al composite by powder metallurgy was described in detail,including powder mixing process (such as ball-to-powder ratio,milling time,milling speed),cold compaction(such as com-paction pressure,pressure-holding time,standing time,etc.),degassing (such as degassing method),heat densifi-cation(such as vacuum hot-pressing,pressureless sintering and hot extrusion,powder hot extrusion),etc. The ef-fects of reinforcement (SiCp) size and interface on the properties of SiCp/Al composites and the strengthening mech-anism of the composites were briefly introduced. Finally the development direction of SiCp/Al composites was fore-casted. |
