摘要
详细阐述了SiC_p/Al复合材料的粉末冶金制备工艺,包括混粉工艺(如球料比、球磨时间、球磨机转速),冷压成形(如压制压力、保压时间、静置时间等参数的选择),除气(如除气方法),热固结技术(如真空热压法、常压烧结热挤压法、粉末热挤压法)等;简述了增强体(SiC_p)尺寸、界面对SiC_p/Al复合材料性能的影响以及SiC_p/Al复合材料的强化机制;最后展望了SiC_p/Al复合材料的发展方向。
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 compaction pressure,pressure-holding time,standing time,etc.）,degassing（such as degassing method）,heat densification（such as vacuum hot-pressing,pressureless sintering and hot extrusion,powder hot extrusion）,etc. The effects of reinforcement（SiCp） size and interface on the properties of SiCp/Al composites and the strengthening mechanism of the composites were briefly introduced. Finally the development direction of SiCp/Al composites was forecasted.
