摘要：
In order to obtain a Al2O3/Al composite with high strength, the Al2O3 generated in situ is served as reinforcement. The ball milling is used to flake pure Al powders. The Al2O3/Al composite with flaked Al powders is obtained by vacuum hot pressing sintering. The effect of the flaked Al powders on the distribution of Al2O3 generated in situ is studied. The hardness and tensile properties of Al2O3/Al composite are studied. The results show that the dehydration temperatures of boric acid in powder mixtures with the flaked Al powders and with the spherical Al powders are 119 degrees C and 128 degrees C, respectively. During sintering stage, the Al2O3 is generated in situ. Compared with the Al2O3/Al composites with the spherical Al powders, more Al2O3 are generated in Al2O3/Al composites with the flaked Al powders. The hardness and ultimate tensile strength of Al2O3/Al composite are higher than those of pure Al alloy.
