在真空感应炉中，９００－１２００℃，以合适的方位将含Ｎ，Ｃ原子的气体注入熔融的含Ｔｉ等的铝合金中，直接原位反应生成０．２－１．２μｍ的ＡｌＮ和２─５μｍ的ＴｉＣ粒子．均布于铝合金基体中，制成性能优异的复合材料．本工艺具有增强颗粒生成速度快的特点．关键词
The better aluminum alloy composite reinforced with AIN-TiC particulates,by in situ reaction, was prepared as follows: an aluminum alloy, containing Ti and others,was melted at temperature ranged from 900 to 1200℃ , and the gaseous atomic nitrogen and carbon flow was injected by proper manner into the melting Al so that AIN (0. 2-1 .2μm) and TiC (2-5μm) formed by in situ reaction dispersed in aluminum matrix homogeneously.Correspondent: CUI Chunxiang,(Institute of Composite, Shanghai Jiaotong University, Shanghai 200030)
