Abstract

The results of the study of the effect of quenching on the structure, physical-mechanical and operational properties of the alloy VK10 OM after the sintering under different technological conditions are presented. It is shown that quenching reduces microporosity in the alloy structure and increases its physical and mechanical properties to a greater extent on the surface than in the sample volume, especially in the case of vacuum sintering. It is shown that increasing the operational stability of the incisors after the quenching in the conditions of continuous casting of steel 45 correlates with the increase of the properties of the alloy and the decrease of adhesive interaction of it to the treated material. The rigging does not affect the residual microporosity, physical-mechanical and operational properties of the alloy after vacuum-compression baking under pressure of gas up to 2.5 MPa.
