Specific features of structure formation in high-nitrogen austenitic steels in quenching
2011
The effect of a heat-treatment regime on the formation of a grain structure in a high-nitrogen chromium-nickel-manganese austenitic steel of two heats, which differ in the addition of strong nitride-forming elements (vanadium, niobium) in steel, is studied. It is shown that the holding temperature and time can be chosen to obtain a grain structure with the same size parameters. The results can be sued to determine the boundaries of the temperature-time regimes at which the efficiency of vanadium and niobium alloying of the steel to retard the grain growth is retained.
