| Abstract: | | 1. | Mechanicothermal treatment of steel 12Kh1MF under the conditions given increases the dispersity of carbide particles without changing the phase composition of the metal and produces a polygonized substructure. The structural changes lead to an increase in the short-term strength characteristics of the steel at standard and high temperatures (up to 650°C). | | 2. | Mechanicothermal treatment increases the time to failure of steel 12Kh1MF by 200–400% at all static stress levels tested. |
