Preparation of Carbide Composites for Ti-C-Mo system by HPCS(High-Pressure self-Combustion Sintering) Process

ABSTRACT

TiC-Mo2C composites were prepared from Ti-C-Mo system by HPCS which has a great advantage of simulataneous synthesis and sintering In this study physical properties and microstructures of the com-posites were measured and observed to compare the sintering effects of Ni and Co each other : The results showed that the role of 5 wt% Ni in the sintering of the carbide composites was superior to that of 5wt% Co and the optimum content of Mo in the Ti-C-Mo system was 20wt% The carbide composites prepared under these two conditions had the best properties with 1.0% in apparent porosity 97.6% in relative density 19.1GPa in Vickers hardness and 5.3MPa$.$m1/2 in fracture toughness.
