Аннотация:Using transmission electron microscopy and X-ray diffraction, a detailed study of the phase transformations in the Fe–Cr system in the alloys Fe-30; 40 and 47 wt.% Cr has been conducted. Since the phase transformation “ordering-separation” occurs on a level of changes in the electronic structure, it can be assigned as a phase transition of the second kind. It takes place in the Fe–Cr system at 900 ± 50 °C and 560 ± 10 °C. The temperature, at which the phase transformations “order–disorder” take place including “separation-solid solution” and “ordering-solid solution”, have been refined. An improved version of the Fe-rich portion of the Fe–Cr phase diagram is presented.
