Studies on SiC Whisker/Al Composites
-
摘要: 本文工作集中于SiCw/Al复合材料的制备、材料的微观结构分析和高温瞬时拉伸试验三方面。结果表明,用高压铸造法制造SiCw/Al复合材料是可行的。用该方法制得的复合材料造价低廉,界面结合良好,具有优良的室温、高温强度和足夠的塑性。Abstract: The manufacturing process for the metal matrix composites of SiC whisker/aluminum alloy is being developed.The process consists of the fabrication of the whisker's preform and the fabrication of the composite billet by liquid metal infiltration.In this way the composites with 17% volume fraction of SiC whisker are manufactured.
