Popis:	Issues of obtaining chrome die steels for cold deformation from sprayed powders have been considered. The blanks are obtained in a gasostatic capsule covered with powder at a pressing temperature of 1100-1150C at a pressure of 1400 MPa with isothermic exposure of 1-2 hours. It has been discovered that powdered vanadium-doped (˜ 8%) and chromium-doped (˜ 4%) die steels do better in high loads. Mouldability of powdered die steel types KH12M and KH12MPH1. It has been found that mouldability of powders greatly depends on their relative poured bulk density (PBD). To increase mouldability, it is advisable to deformation-process and finally annealoriginal powder.
