| 摘要 |
The invention relates to ferrous metallurgy, namely to a method for heat treatment of steel. A method for heat treatment of steel comprises its heating in inter-critical range of temperatures, soaking, subsequent cooling in water to the range of temperatures of formation of lower bainite, further cooling of steel inrange of temperatures on air or soaking in furnace at constant temperature with subsequent cooling on air, then additionally quenching of steel surface is carried out with hating above Асusing of high-frequency currents, or sources of concentrated energy, and low drawback. The invention provides for the improvement of level strength, plastic properties and impact elasticity of steel. |
