Claims (1)

Способ термоциклической обработки низколегированных и углеродистых сталей, включающий многократные нагревы и охлаждения, отличающийся тем, что нагрев производят до температуры гомогенизации аустенита со скоростью 3 - 5 град/мин, а охлаждение - со скоростью, обеспечивающей сорбитное или мартенситное или бейнитное превращения до температуры на 50 - 100oC ниже температуры сорбитного превращения (Ar1 или МК или Бк).A method for thermocyclic treatment of low alloy and carbon steels, including multiple heating and cooling, characterized in that the heating is carried out to the temperature of homogenization of austenite at a speed of 3-5 degrees / min, and cooling at a speed that provides sorbitol or martensitic or bainitic transformation to a temperature of 50 - 100 o C below the temperature of the sorbitol transformation (Ar 1 or MK or B to ).
