Changes in the Specific Heat of U8 Steel after Quenching by Deforming Cutting during Its Heating to 400°C

Resumo

The specific heat of U8 steel is measured after deforming cutting, quenching from furnace heating into water, and subsequent heating in a calorimeter in the temperature range 100–400°C. The temperature dependences of the specific heat after deforming cutting and furnace quenching have substantially different characters, which is due to a nonequilibrium state of the structure in the material after quenching by deforming cutting. The change in the enthalpy of U8 steel during its heating for these types of quenching is calculated.
