## Abstract

The kinetics of phase transformations at cooling of carbon steel in dependence on the temperature of preliminary annealing T$\_{an}$ is studied. It is shown that the cooling from T$\_{an}$ \> A$\_3$ (i. e. above the temperature of ferrite start) with the rate 90 - 100 K/s results in structural state which essentially dependent on T$\_{an}$; at 750$^0$C \< T$\_{an}$ \< 830$^0$C the transformation is of perlite type whereas at T$\_{an}$ \> 830$^0$C the martensitic structure arises. Our results evidence the formation of a special structural state in a certain range of temperatures near and above the boundary of two phase region which is characterized by a substantially nanoscale heterogeneity in carbon distribution, lattice distortions, and magnetic short-range order.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
