摘要
用复合铸造法制备的SiC_μ/Al复合材料,加热到一定温度并保温不同时间以改变其界面反应程度,通过确定复合材料中的分含量及其与温度和时间之间的相互关系,对界面反应动力学进行了研究,并导出动力学方程,由此求出反应动力学的参数。
SiCp/Al composites fabricated by compocasting method was heated to different temperatures and held for a certain period in order to change interfacial reaction degree. The interfacial reaction kinetics was studies by determining silicon concentration in the composites and its relation with two effecting factors, temperature and time. A dynamic equation was derived and several parameters which have definite physical implication were calculated from the equation, such as the starting temperature of the interfacial reaetion, velocity constant of the interfacial reaction and so on.
