| 摘 要： | 以Al、TiO2、C为原材料,用接触反应法制备了TiC-Al2O3P/Al复合材料,采用XRD和SEM手段测定了材料的相组成、组织形貌及相分布,分析了碳含量对组织的影响。试验结果表明,该复合材料主要由分布于Al基体中的球状或近球状的TiC颗粒、不规则的Al2O3颗粒和少量的TiAl3组成,且随含碳量的增加,TiAl3减少;当C和TiO2比超过1.5后,TiAl3基本消失,但出现TiC2相。

| Abstract: | TiC-Al_2O_(3P)/Al composite was synthesized by contact reaction technique using TiO_2,Al,and C powders as raw materials.The phase composition and distribution,as well as the microstructure of the composites were investigated by means of X-ray diffraction(XRD) and scanning electron microscopy(SEM).The effect of carbon on microstructure of the material was studied.Experimental results show that the composites are composed of spherical or near-spherical TiC particles,irregular Al_2O_3 particles and acicular Ti... |
