The degree of dissolution of carbides, nitrides, and carbonitrides in steels during austenitizing determines grain size, the effectiveness of dispersion hardening, and the subgrain structure of steels, i.e., the main structural factors on which the b

1. With a decrease in quenching rate from the intercritical temperature range a change from a ferritic-martensitic to a ferritic-bainitic structure occurs in 05G2S2 steel. At the same time there is an improvement in the combination of characteristics

The processes of diffusion interaction of vanadium carbides with cast and powdered steels are largely analogous. Differences are mainly due to unequal diffusional mobility of the components in cast and powdered materials.
