摘要：

A new process is proposed to fabricate an intermetallic compound-reinforced aluminum alloy matrix composite using the reaction between porous nickel and molten aluminum alloy. The intermetallic compound-reinforced aluminum alloy composite was manufactured with the infiltration process method. Porous nickel reacted with the molten aluminum alloy at 973 K, and the intermetallic compound of Al3Ni was generated on the surface of the porous nickel. The generated intermetallic compound Al3Ni is delaminated due to different thermal expansion coefficient with nickel and moves in the direction of aluminum matrix. The effects of processing variables such as specific surface area of porous nickel, holding time after infiltrated molten aluminum alloy, and cooling rate on the formation and dispersion behavior of Al3Ni were investigated.
