基于Al-SiO 2 和Al-SiO 2 -C制备的铝基复合材料微观组织与力学性能
发布时间：2021-04-23 10:03
本文以Al粉,Si O2粉和C粉为原料,制备Al2O3,Si C和Si为增强相的铝基复合材料。同时研究了Al-Si O2和Al-Si O2-C两种体系,采用球磨和反应热压法制备铝基复合材料。用低能球磨原料粉,然后在真空热压炉中烧结以合成新的增强相。对于Al-Si O2体系,分别用低能球磨和反应热压法合成了增强相体积分数为10,20和30%的复合材料。研究了增强相体积分数对微观组织和力学性能的影响。当体积分数为10vol.%和20vol.%时,微观组织观察表明原位反应生成的Al2O3和Si均匀分布在铝基体上,并且增强相尺寸细小,小于2μm。而当增强相的体积分数为30vol.%时,可以观察到Al2O3尺寸达到2μm和块状初晶硅(（130μm）。利用DTA研究Al-SiO2和Al-Si O2-C两种体系的反应机制。加热到900oC保温1小时,足以使Al和Al O2发生完全反应,生成Al2O3和Si。然而,将C加入到AlSi O2体系中,反应产物除了Al2O3和Si,还有Al4C3和Si C生成。原位反应生成的Al2O3,Si C,Al4C3和Si均匀分布于铝基体上,尺寸...
