| 摘 要： | 选用不同粒径大小的SiC颗粒,并通过对颗粒分布的有效控制,采用无压浸渗工艺制备了不同体积分数(15%～65%)的SiCp/Al复合材料,并在此基础上试制了梯度SiCp/Al复合材料.运用OM,XRD等手段对所制备的复合材料进行了显微组织观察与成分分析,并对选定体积分数的复合材料进行了密度以及力学测试.研究结果表明,无压浸渗工艺下不同体积分数的SiCp/Al复合材料组织均匀、致密,力学性能良好;具有梯度结构的SiCp/Al复合材料层间结合良好,没有层间剥离现象.

| Abstract: | Using SiC particles with different diameter,by effectively controlling the distribution of SiC particles,SiCp/Al composites with different SiC volume fraction(15%~65%) were fabricated under pressureless infiltration processing.In addition,compositional graded SiCp/Al composites were also fabricated in the same way.The microstructure of SiCp/Al was studied by means of OM,XRD.Besides,density test and mechanical test were carried out on selected SiCp/Al composites.According to the study,SiCp/Al composites with different SiC volume fraction by pressureless infiltration possess have even and compact microstructure as well as fine mechanical property.Moreover,the interface between layers of compositional graded composites integrates well and there is no delamination. |
