Special features of the structure and properties of cast high-speed steel R6M5
cooled from a solid-liquid condition at various rates are considered. Liquid
metal is cast into a permanent graphite mold heated to 20, 300, and 600°C and
cooled in open air or in liquid nitrogen. It is shown that with increase in the
cooling rate the degree of alloying of the solid solution and the amount,
