A new process, based on an infiltration and reaction method, is proposed to fabricate metal matrix composites reinforced with Al3Ni, intermetallic compounds. This study investigates the optimum conditions for refining intermetallic compound dispersion inside the metal matrix at the different reaction times (60 s, 300 s and 600 s) at molten alloy temperature of 973 K and applied pressure of 0.1 MPa; porous nickel with a specific surface areas of > 5800 m2/m3 was used. The counts, area fraction, and aspect ratio of the intermetallic compounds inside matrix are investigated by different of reaction times. In additions, Vickers hardness, three-point bending strength and thermal conductivity of intermetallic compounds reinforced matrix composites are investigated.
