A new process, based on an in ltration and reaction method, is proposed to fabricate metal matrix composites reinforced with Al 3 Ni, intermetallic compounds. This study investigates the optimum conditions for re ning 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 speci c surface areas of > 5800 m 2 /m 3 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.

“…The shape of the intermetallic compound changed from needle to granular when specific surface area of porous nickel increased from 120 m 2 /m 3 to >5800 m 2 /m 3 . 18 Yang et al fabricated in situ Al 3 Ni particle-reinforced A356 alloy matrix composites from an Al-Ni 2 O 3 system via the melt reaction method. The results indicated that the Al 3 Ni particles formed in dot-like, block, strip, and ball shapes, according to the different weight percentages of Al 3 Ni in the composites.…”

Recently, Ti–Al intermetallic compound-reinforced Al matrix composites have attracted increasing attention because of their high specific modulus, strength, and thermal stability. In this study, blended powders of Ti and Al were ball milled and fabricated to in situ Ti–Al intermetallic compound-reinforced Al matrix composites by cold-pressing and hot-pressing sintering. The microstructures and component of core–shell-like structure in reinforcement were observed and analyzed. Material properties including hardness, density, and compression performance were tested and analyzed according to experimental processes. The results indicate that the time point of compression in hot-pressing sintering is crucial to obtain the closed core–shell-like structures. Based on the orthogonal experimental data, entropy methods and technique for order preference by similarity to ideal solution were combined to select the process parameters (ratio of Ti and Al, milling time, sintering temperature, holding time, and compaction pressure) for the best comprehensive performance of Vickers hardness and compressive yield strength.
