| description | This paper presents the results of a Mössbauer spectroscopy investigation of the processes in the binary alloys Fe<sub>100−<i>c</i></sub>Cr<i><sub>c</sub></i> (<i>c</i>, at. % = 6.0, 9.4, 13.2) and of the short-range (SR) atomic ordering accelerated by applying warm severe plastic deformation via high pressure torsion (HPT). After warm HPT treatment, in the vicinity of the concentration <i>c</i> = 9 at. %, there was revealed to be an inversion of the sign of the SR order, the anomaly of the formation of a Fe–Cr solid solution, which was predicted ab initio and is observed at long-term anneals and exposures to irradiation by electrons. The acceleration of the SR ordering at HPT is due to the continuous generation and a large number density of mobile point defects. |
