摘要
制备了Al2O3/Al-Cu和Al2O3/Al-Cu-Si原位复合材料,采用SEM观察显微组织,XRD分 析物相,EDS分析相所含元素.初步结果表明,原位合金化和原位颗粒共同强化金属基体是可 行的,合金元素Cu和Si出现在基体中,细小增强颗粒Al2O3呈弥散分布.
Al2O3/Al-Cu and Al2O3/Al-Cu-Si composites are fabricated from in-situ reaction Al+CuO and Al+CuO+SiO2 respectively. SEM observation of the morphologies of the materials, XRD analysis of the phases, and EDS analysis of elements in the phases are performed. Primilinary results show that alloy elements Cu and Si are presented as predicted, as well as fine and homogeneously distributed Al2O2 particles formed, which indicate that the newly developed concept is feasible.
