Abstract

Abstract A heat resistant and wear resistant alloy of the carbidedispersion and precipitation-hardening type, to be used for cutting tools, etc., has a basic composition consisting, in weight percent based on the total weight of said alloy, of from 10 to 90 percent dispersed particles composed of one or more kinds of carbides or composite carbides of transition metals from Groups 4a, 5a and 6a and the balance being from 70 to 90 percent Ni, from 2 to 10 percent Ti and 0.5 to 10 percent Al, and one or more kinds of alloy elements selected from the group consisting, in weight percent based on Ni-base matrix, of no more than 10 percent Ta, no more than 10 percent Nb, no more than 20 percent W and no more than 20 percent Mo.
