Abstract

In-situ TiC particle reinforced ZA70 composites have been fabricated by adding the Al-Ti-C powder blocks into molten aluminum ZA70 alloy.It was found that the co-presence of brittle Al3Ti flakes with TiC particles is observed in the composites with melting at 900 ℃,while the presence of TiC particles can be only observed in ones with the melt temperature increased to 1 300 ℃.Occurrence of TiC particles can improve the strength at room and high temperatures and slightly deteriorate the elongation of the composites.However,the formation of Al3Ti flakes can weaken the strengthening effects of TiC particles.

摘要

采用原位合成法将Al-Ti-C粉末预制块加入到ZA70熔体中

成功制备了TiC颗粒增强ZA70铝基复合材料

研究表明:在900℃熔炼温度下

复合材料中有长条状中间相Al3Ti相存在

而在1300℃熔炼温度下

复合材料中只有TiC颗粒形成;TiC颗粒的加入提高了复合材料的室温和高温强度

但伸长率略有下降

但Al3Ti相存在会削弱TiC颗粒的强化效果。

Abstract

while the presence of TiC particles can be only observed in ones with the melt temperature increased to 1 300 ℃.Occurrence of TiC particles can improve the strength at room and high temperatures and slightly deteriorate the elongation of the composites.However

the formation of Al3Ti flakes can weaken the strengthening effects of TiC particles.
