STUDY OF FORMATION OF THE GRAIN OF AUSTENITE STEELS IN DIFFERENT SYSTEMS OF ALLOYING
In this paper study a series of steels for the propensity to collectively increase the austenite grain. The features of rapid austenitizing in salt baths of low-carbon martensitic steels with an increased the resistance of the diffusion relaxation. The principal possibility of the progressive realization of isothermal holding at 3 stages of structure: inheritance structure during the incubation period of recrystallization, primary recrystallization to produce superfine austenite grains and recrystallization. The ability to stabilize the grain boundaries after the primary recrystallization by varying the parameters of the carbide phase.
