Изобретение относитс к области металловедени .This invention relates to the field of metallurgy.
Известен способ обработки стали, состо щий в закалке ее и последующем упрочнении на стадии отпуска. Однако он применим дл высоколегированных хромистых сталей.There is a method of steel processing, consisting in its hardening and subsequent strengthening at the tempering stage. However, it is applicable to high alloy chromium steels.
Цель изобретени .- повышение прочности и сохранение пластичности легированных малоуглеродистых сталей с относительно небольшим содержанием легирующих элементов. Это достигаетс , тем что перед закалкой провод т химико-термическую обработку и пластич.скую деформацию осуществл ют на 40-80%. Получают в поверхностном слое структуру наклепанного нестабильного аустенита, претерпевающего при натружеиии превращение оптимальной интенсивности. В результате испытании малоЗТлеродистых легированных сталей получают следующие свойства: Предел текучести, кг/мм 130The aim of the invention is to increase the strength and preserve the ductility of alloyed low carbon steels with a relatively low content of alloying elements. This is achieved by the fact that, before quenching, chemical-thermal treatment is carried out and plastic deformation is carried out by 40-80%. A structure of a riveted unstable austenite, which undergoes transformation and an optimal intensity transformation, is obtained in the surface layer. As a result of testing low-carbon alloyed steels, the following properties are obtained: Yield strength, kg / mm 130
Предел прочности, кгс/мм155Strength, kgf / mm155

Относительное сужение, %56Relative narrowing,% 56
Ударна в зкость, кгм/см 7Impact viscosity, kgm / cm 7
