ENG: On the example of the carbon steel, issues of
structuring in the process of accelerated cooling are considered.
The emerging gradient of structures at different distances from
the surface of the heat transfer is presented in the form of a
dependence, which is adequate to the effect of the temperature of
individual heating during the release of steel after the quenching.
It is shown that after the forced cooling is stopped, the increase
of distance from the cooling surface accompany higher the
tempering temperature of the metal. In the volumes of the metal,
the microstructure close to the middle of the disk wheel is formed
by the diffusion mechanism.
