WC_p/2024铝合金复合材料界面反应的分析 杨剑1,梁秋实1,杜军1,毛昌辉1 (1.北京有色金属研究总院先进电子材料研究所,北京,100088) 摘要:采用真空热压法在不同温度下制备了体积分数为12%的WC_p/2024Al复合材料,试验中所用WC原始粉末的平均粒径分别为2μm和8μm.利用XRD,SEM,EDS等方法对增强颗粒与基体金属之间的界面反应进行了研究.结果表明,界面反应的主要产物为WAl12,但是当制备温度较高时,界面反应产物中出现少量Al_5W,并且WC_p(2μm)/2024Al复合材料界面反应的起始温度低于WC_p(8μm)/2024Al复合材料.硬度测试结果表明,界面反应发生后,复合材料的硬度提高,最高比例达50%. 关键词:铝基复合材料; 界面反应; WC颗粒; 真空热压; aluminium matrix composites......
