Abstract

Fabrication and characterization of aluminum MATRIX COMPOSITES different volume fractions of Ni3Al powder (50-4 vol%) were investigated. Ni3Al powder was produced by mechanical alloying of elemental nickel and aluminum power mixture. Al-Ni3Al composite parts were prepared using a powder metallurgy route involving two stages; Al and Ni3Al powder mixture were first compacted under 500Mpa and then hot-pressed under 250MPa at 420°C for 10min. The microstructure and hardness of consolidated parts were investigated by x-ray diffractomerery, optical and scanning electron microscopy and hardness measurement. Results showed that consolidated Al-Ni3Al Al samples included significant porosity with a nearly uniform distribution of Ni3Al particles. Additionally, structural examinations showed that no significant reaction between Ni3Al and aluminum matrix occurred during sintering process. Al- Ni3Al Al composites exhibited a higher hardness value compared with pure aluminum sample prepared under identical conditions. The hardness value of Al- Ni3Al Al composites increased linearly as Ni3Al content increased.
