摘要： Disclosed are composition and a method for making a high volume reinforced Al composite by use of a dipping process. Through the method comprising mixing 20-50 wt % of exothermic reaction-causing Ti and C or Ti and B powders, 20-60 wt % of exothermic reaction-controlling diluent powders, and 5-30 wt % of infiltration-aiding Al or Al alloy powders, then preparing mixture powders; preforming the mixture powders into a predetermined shape; fitting the preformed body in a reaction container, followed by dipping in an Al melt of 700-1,100° C.; and separating the synthesized composite from the reaction container after removal from the Al melt, a high volume reinforced Al composite can be prepared from the mixture powders through such exothermic synthesis in a metal melt that reinforced particles are uniformly distributed while restraining the generation of pores. As such, the exothermic reaction-controlling diluent powders are selected from the group consisting of TiC, TiB2, SiC, WC or mixtures thereof.
