摘要

主要讨论Al-TiO

-B

系XD法制备铝基复合材料的合成工艺及其反应机理。结果表明:在B2 O3 与TiO2 摩尔比小于1时

真空炉温预热至10 0 0K左右时压坯爆燃

反应产物由TiB2 、Al3 Ti和Al2 O3 组成

其中Al3 Ti为棒状物

TiB2 、Al2 O3 为细小颗粒

粒径为数μm左右。同时分析了球磨时间、预紧实度对反应产物的影响规律。

Abstract

The synthesis process and mechanism of aluminum matrix composites fabricated by XD method in Al-TiO

2-B

3 reaction system were investigated.The results indicated that the green perform combusted at the temperature of 1 000K and the reacted products were composed of grains Al

3 and TiB

2 and rod-like Al

3Ti phase

when the B

3/TiO

2 mole ratio was less than one.The effect of milling time and green density on the product structure were also discussed.
