P/M products are provided having improved resistance to wear and abrasion by adding controlled amounts of pre-alloyed refractory carbide material to metal powders selected from the group consisting of iron-base, nickel-base, aluminum-base, copper-base and beryllium-base powders following which the mixed powders are compacted and sintered to the desired shape.

Sintered P/M products containing pre-alloyed titanium carbide additives

A sintered titanium carbide tool steel composition is provided comprising by weight about 15% to 40% primary grains of titanium carbide dispersed through a steel matrix making up the balance, the composition of said steel matrix consisting essentially by weight of about 3% to 7% chromium, about 2% to 6% molybdenum, about 2% to 8% nickel, about 0.2% to 0.6% carbon and the balance essentially iron.

Titanium carbide tool steel composition for hot-work application

Relates to a sintered age-hardenable titanium carbide tool steel comprising by volume about 15% to 50% primary grains of titanium carbide dispersed through a high cobalt-containing steel matrix making up the balance, said matrix consisting essentially by weight of about 10% to 25% cobalt, about 5% to 20% chromium, about 0.5% to 5% molybdenum, 0 to 2% nickel, 0 to 0.15% carbon and essentially the balance at least about 50% iron.

Age-hardenable titanium carbide tool steel

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 and containing a small but effective amount of misch metal ranging from about 0.1 to 1.25% by weight of said matrix sufficient to effect a substantial improvement in said properties.

Titanium carbide tool steel having improved properties

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.
