Abstract

Studies have been carried out to study the process of high-voltage electric-discharge sintering of powder of high-speed steel R6M5. The process of high-voltage electric-discharge sintering of powders is accompanied by a complex of electrophysical, thermodynamic and mechanical phenomena that affect the sintering processes of samples and their properties.

 It was found that the process of high-voltage electric-discharge sintering of powders of P6M5 steel is accompanied by compaction of the powder as a result of sintering of particles, as well as by the action of compressive stresses on the sample from the powder.
The shape and size of particles, the nature of surface films, the size and shape of the matrix have a great influence on the process of high-voltage electric-discharge sintering.

Factors affecting the strength properties of samples include the particle size distribution of the powder, its initial electrical resistance, and technological processing parameters, such as discharge energy and discharge current density.
