Abstract

1,138,921. Sintered cemented carbides. FORD MOTOR CO. Ltd. May 16, 1967 [June 14, 1966], No. 22675/67. Headings C7A and C7D. A sintered cemented carbide is formed by sintering a compacted powder mixture of WC, C and a bonding metal consisting essentially of Fe alloyed with 5-40% by weight of Ni, the C content of the mixture being sufficient to prevent the formation of an eta phase and insufficient to precipitate graphite, the initial WC grainsize and the sintering conditions being such that the final grain size of the WC is not more than 5 microns. Part of the Ni may be replaced by Co and part of the added C may be present in the added bonding metal. The sintered compact may be heat treated to produce a martensitic structure in the bonding metal with a consequent hardening effect.
