Abstract : The composites design goals to have combined properties of each of the materials component. Different materials composition between metals, ceramics, and polymers can change the composite properties. In this research, metal matrix composite was selected to be aluminum as matrix phase while the reinforced materials were selected to be Nano particles Titanium carbide and different volume percentage of aluminum oxides (whiskers). All specimens were fabricated one time by annealing and another time by hardening heat treatment process. It was found that the heat treatment process, Alumina particle sizes, and Alumina weight percentage have sever and significant effect on the measured mechanical properties; ultimate tensile, compressive strength and hardness of the metal composite while it have minor effect on the material ductility represented in the measured elongation percentage.

Keywords : Metallic composite, metal matrix, Titanium carbide, Aluminum oxide particle size, Reinforced material,
