SHS-快速加压合成TiC,Al_2O_3/Al复合材料的工艺研究

Study on Fabrication Technology of TiC,Al_2O_3/Al Composites by SHS-Rapid Pressing Method

利用SHS反应-快速加压的方法制备了Al2O3，TiC／Al复合材料，研究了在不同Al、Al2O3加入条件下燃烧反应的特征及制备的Al2O3，TiC/Al复合材料的相，组织特征．发现一定过量Al的存在对材料的致密化作用明显，在过量w（Al）为10％时，获得的材料相对密度达到97.5％，抗弯强度提高约20％

Tge TiC, Al2O3/Al composites were prepared by combustion reaction-rapid pressing.The phase and microstructure characteriastics of TiC, Al2O3, bciroirate abundent Al have played a great role in densification of composites. The relative density and the inflecting strength of the composites went up to 97.5% and 20%, when Al is 10wt%.
