Abstract
Data are given concerning the opportunity of applying barocryodeformation (plastic deformation under the conditions of severe uniform compression at cryogenic temperatures) to produce ultrafine-disperse martensitic structure in Kh18N10T steel (≤0.08 C, 18 Cr, 10 Ni, <0.7 Ti, ≤2 Mn, ≤0.8 Si (wt %)), which ensures an increase in the physicomechanical characteristics of material that are unattainable when using other types of treatment. Experiments are described that make it possible to explain the high (in spite of the presence of large forces of uniform compression) rate of completion of the martensitic transition upon the deformation of the steel under such conditions.
