Paper Title:
Formation of Titanium Carbide Reinforced Copper Matrix Composite by In Situ Processing
  Abstract

Composite materials with copper matrix and ceramic particle reinforcements provide basis for producing relatively high hardness and electrical conductivity materials. Most of the work on copper-based composites has involved transition metal carbide reinforcement, which is introduced in the copper matrix through a powder metallurgy (P/M) route. TiC particle is one of the interesting candidates for the reinforcement of the Cu composite. This is because of its high melting point, high hardness, good oxidation and corrosion resistance combined with good electrical and thermal conductivity. In this study, in situ prepared copper-titanium carbide using high energy ball milling was addressed. Cu-Ti-C mixture powder was mechanically alloyed by high energy ball milling at 400 rpm speed for 4 hours to investigate the formation of TiC phase during milling. Then, MA was continued for 5, 20, 40,60 and 80 hours in order to determine the formation of titanium carbide phase by milling time. Then the as-milled powders were compacted at 400 MPa and sintered at 900°C for one hour. As-milled powder was characterized by x-ray diffraction for phase identification. From the XRD result, TiC peaks were found at 35.9˚, 41.7˚and 60.4˚.
