Production method of intermetallic porous perform for reinforcing of composite materials were elaborated. Mixture of aluminum and titanium powder was cold isostatically pressed (CIPed) and such produced cylindrical pill was ignited in microwave field. Obtained structures usually have open porosity what making them enables for pressure infiltration with molten metal. The investigations of the structure revealed uniform morphology and globular structure of Al-Ti compound which achieved much higher microhardness than substrates. Obtained perform can be widely used as the reinforcement to produce hybrid composite materials by the infiltration method. Aluminum casting alloys can be locally reinforced to improve hardness and resistance to oxidization at high temperature.
