Conclusions
Hot extrusion of high-speed steel powder enables metal of 100% density to be obtained. The quality of P/M 10R6M5K5 high-speed steel produced by hot extrusion of powder, as assessed by all the indicators investigated, is comparable to that of the same steel produced by hot gasostatic pressing followed by forging.
