| 摘 要： | 本文首次提出控制压铸SiCP/6061Al 复合材料中轻微界面反应的方法, 并就反应的机理及其对材料弹性模量的影响规律和机制进行了研究。结果表明: 界面反应物为离散分布的小颗粒状MgAl2O4, 反应中氧的主要来源为原始态SiC 颗粒表面残留的SiO2薄层; 该种反应物的存在有利于材料弹性模量的提高。

| Abstract: | The present paper reports the authors first finding concerning the method of controlling a slight interfacial reaction in SiCP/6061Al composite fabricated by squeeze casting. Reaction mechanism and reaction effect on the Youngs modulus of the composite were studied. The results indicate that the interfacial reaction products are isolated small particles of MgAl2O4. The principal supply of oxygen in reaction is the residual thin SiO2 layer around the as received SiCParticles. The existence of reaction product found in the study has a beneficial effect on the Youngs modulus enhancement of the composite. |
