Tooling materials science| Summary: | The task of the scientific research was to study the peculiarities of the effect of uniaxial compression on the formation of the structure of the medium-grained WC–20%Ni alloy.
It is shown that there is a method that makes it possible to improve the structural parameters of the WC–20%Ni hard alloy, which ensures an increase in the operational performance of the material. It is claimed that the directed action of uniaxial compression makes it possible to significantly improve the nature of the mutual arrangement of carbide grains. Such improvements lead to an increase in the physical and mechanical characteristics of the hard alloy. The paper presents the results of the study of the formation of the structure and properties of the alloy at a sintering temperature of 1350°C under the action of uniaxial compression from zero to 1.6 MPa. |
