ABSTRACT:
A sintered steel-bonded titanium carbide composition characterized by an improved combination of physical and anti-friction properties is provided comprising about 15% to 60% by weight of primary grains of titanium carbide dispersed through a steel matrix making up essentially the balance, the steel matrix being characterized metallographically by an austenitic decomposition product, said steel-bonded titanium carbide composition containing an effective amount of a grain-growth inhibitor ranging by weight from about 0.25% to 2% of a columbium-group carbide.
