ABSTRACT:
A titanium-base sintered alloy which comprises a TiC and/or TiN or Ti(C,N) solid solution accounting for 5 to 70 vol %, with the remainder being composed of two components. The first component is at least one species selected from the group consisting of Groups Va and VIa metallic elements, except Cr, or at least one species selected from the group consisting of carbides, nitrides, and carbonitrides of Groups Va and VIa metallic elements, except Cr. The second component is titanium. The first component accounts for 1 to 30 vol % and the second component accounts for 70 to 99 vol % of the total amount of the first and second components. The alloy produces a preferred result when the content of TiC or TiN is 35 to 70 vol % and the first component accounts for 1 to 15 vol % of the remainder. It is desirable that the TiC, TiN, and the first component of the remainder be in the form of a solid solution. This alloy exhibits improved wear resistance, strength, and specific strength without any loss in corrosion resistance.
