FIELD: tool making industry branch, namely plastic working of materials.
SUBSTANCE: in order to improve metal using factor, to increase wear resistance of tool, steel (P6M5) blank. Is heated up to 830°C and it is deformed in isothermal mode at rate 10-3 s -1 and at deformation degree 60%. Then blank is subjected to deformation at 765°C at rate 10-3 s-1 and at deformation degree 40%. According to invention strength of tool made of deformed blanks exceeds by two times strength of tool made in accordance with well known process.
EFFECT: improved strength of tool made of worked steel blank.
