Abstract
The paper presents comparison of results of investigations into phase transformation in W-Mo-V-Co type 11-0-2-5 and W-Mo-V type 11-0-2 high- speed steels. The maximum hardness respectively 66 HRC and 64.5 HRC in vestigated steels have after quenching at the temperature of 1240 degr ees C and tempering at the temperature of 540 degrees C. Secondary har dening in these steels is due mainly to precipitation of fine M4C3 car bides and also to martensitic transformation of retained austenite int o alpha phase.
