ABSTRACT

Hardening of sintered carbides from 1300°K and more may lead to a change in the phase composition of the alloy under conditions of long holds at the hardening temperature. With an increase in hardening temperature there is an increase in the solubility of tungsten in the binder phase and an increase in stresses in the carbide and cobalt phases. An increase in hold time causes practically no change in the tungsten content in the binder but causes an increase in stresses in the phases, which may cause the appearance of some quantity of α-Co. The optimum heat-treatment cycle for sintered carbides corresponds to the maximum solubility of tungsten in cobalt with the minimum change in phase composition and stressed state of the phases.
