摘要
应用反应合成工艺制备了自生TiCP/Al 4Cu复合材料。通过XRD分析了自生TiCP/Al 4Cu复合材料的相组成 ,用SEM观察了自生TiCP/Al 4Cu复合材料的微观组织和断口形貌 ,测试了自生TiCP/Al 4Cu复合材料的力学性能。结果表明 :自生TiCP/Al 4Cu复合材料增强颗粒细小圆整 ,在基体中分布均匀。
In situ TiC p/Al 4Cu composite was prepared by reactive synthesis technique. The phase constituent, microstructure and fracture morphology have been observed by means of XRD,SEM. The mechanical property and fluidity of TiC p/Al 4Cu composite was tested. The results showed that the finecircular reinforced particulates in TiC p/Al 4Cu in situ composite distribute hamegeously into the matrix and no reactive layer in the interface surface between reinforced particulate and matrix. The composite has excellent comprehensive mechanical properties under T6 heat treated state. The fluidity of composite increases with the increase of temperature and decreases with the increase of volume fraction of reinforced particulates.
