Aluminum Matrix Composites reinforced with
\r\nnanocrystalline Ni3Al carbon-coated intermetallic particles, were
\r\nsynthesized by powder metallurgy. Powder mixture of aluminum
\r\nwith 0.5-volume fraction of reinforcement particles was compacted
\r\nby spark plasma sintering (SPS) technique and the compared with
\r\nconventional sintering process. The better results for SPS technique
\r\nwere obtained in 520ºC-5kN-3min.The hardness (70.5±8 HV) and the
\r\nelastic modulus (95 GPa) were evaluated in function of sintering
\r\nconditions for SPS technique; it was found that the incorporation of
\r\nthese kind of reinforcement particles in aluminum matrix improve its
\r\nmechanical properties. The densities were about 94% and 97% of the
\r\ntheoretical density. The carbon coating avoided the interfacial
\r\nreaction between matrix-particle at high temperature (520°C) without
\r\nshow composition change either intermetallic dissolution.<\/p>\r\n","references":"[1] M. Rahimian, N. Ehsani, N. Parvin, H.R.
