Abstract

The complex metallic alloy (CMA), Al76.8Fe24, was in-situ synthesized in the Al-based hybrid composite by powder metallurgy technique. The structural analysis by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy indicated that the Al76.8Fe24 CMA phase was formed by diffusion of Fe atoms into the Al matrix during the sintering stage. The formation of the CMA phase was mainly determined by the sintering temperature which was just above the eutectic temperature of Al–Fe. Moreover, the fully dense Al-based hybrid composite was obtained and exhibited ultrahigh strength ∼1100 MPa, indicating that this method is expected to be effective in producing CMA particle reinforced Al-based hybrid composite.
