ABSTRACT:
A cemented carbide composition is disclosed that consists essentially of a carbide of a refractory metal selected from Group 4, Group 5, and Group 6 metals and mixtures thereof and a binder selected from one of the foregoing refractory metals and from 0.5 to 1.5% by weight of an iron group metal. A process for producing these materials is also disclosed which comprises forming an intimate admixture of the desired refractory metal carbide, the desired refractory metal, an iron group metal, a paraffin wax and a volatile mixing aid. Thereafter, the mixing aid is removed by heat. The resulting powder particles are compacted to a predetermined shape and heated at a temperature sufficient to remove the wax and thereafter are heated at a temperature above the melting point of the catalyst and thereafter elevated in temperature to achieve suitable sintering.
