| Abstract: | In-situ (Al_2O_3 +Al_3Ti) reinforced Al matrix composites were successfully fabricated using Al-TiO_2-SiO_2 solid-liquid system. The composites were inspected by X-ray diffraction, the microstructure of the composite was analyzed by scanning electron microscopy. The results indicate that, the in-situ Al_2O_3+Al_3Ti particles reinforced Al matrix composite has dense microstructure. Al_3Ti particulates with spherical shape combining closely with the matrix exhibit finer size and homogeneous distribution in the matrix; compared with Al matrix alloy, the hardness of (Al_2O_3 +Al_3Ti)~P/Al composites obviously enhances. |
