“…Magnetic field plays a vital role in the formation of specific microstructures in the aspect of thermodynamics or kinetics 134. Under the high magnetic fields, atoms are magnetized to exhibit different behaviors 135,136. Ghazisaeidi et al discovered that Mn in the CrMnFeCoNi HEA eliminated the energy difference between FCC phase and HCP phase 28.…”

High‐entropy alloys (HEAs) are based on five or more principal elements with equal or nearly equal molar fractions and possess many significant advantages over traditional alloys, including high strength and hardness, excellent corrosion resistance, outstanding thermal stability, and irradiation resistance. Phase structure plays a vital role in determining the property of HEAs. For further enhancing the performance of HEAs in various application fields, a controllable synthesis with desired phases is required. In this review, the diverse phase structures of HEAs and the related properties are first introduced. Then, alternative tuning strategies to promote the desired phase structure of HEAs are focused upon. Property adjusting of phase‐engineered HEAs is also discussed in depth. Lastly, some insights into the challenges and future prospects in this rapidly emerging research field are provided.

“…В результате этого процессы перераспределения и аннигиляции дислокаций, за счёт которых и происходит разупрочнение, при наложении магнитного поля протекают медленнее. Альтернативное объяснение, представленное в [41], основано на том, что наличие большого количества дислокаций оказывает разориентирующее действие на спиновый порядок в ферромагнетиках, [45 -47]. Поэтому перемещение дислокаций в объеме деформированного материала при наложении магнитного поля замедляется из-за появления дополнительной энергии, которую необходимо затратить для преодоления дислокациями ориентирующего влияния поля [45].…”

Review of relevant research about the effect of high DC magnetic field on structural and phase transformations in different ferromagnetic alloys are presented. Main experimental results of simultaneous impact high temperature and magnetic field with induction up to 45 T on alloys Fe-C, Fe-Co, Fe-Si, Mn-Bi, Fe-Ni, Ni-Co and other are presented. The main high magnetic field effect on a phase transformation is equilibrium temperature changing, which reaches tens degrees. Modern views about cause of such effect, which consist in changing of thermodynamic conditions of transformation under external magnetic field due different magnetic properties between parent and appearing phase are described. In the theoretical and experimental determination of the phase transformation temperature shift magnitude in most cases there is a significant discrepancy. The probable causes such discrepancy are discussed. Moreover, review of results on investigations effect of magnetic field on structure transformations; in particular recovery and recrystallization in cold-rolled ferromagnetic alloys are presented. It is shown, that magnetic field retards recovery process and furthermore promotes preferential formation of certain texture components. Nowadays there is no consensus in the scientific literature on the nature of the observed effects. In this paper, critical analyses of the approaches proposed by different authors to the interpretation of experimental results are presented. The current state of the problem is described; in conclusion, the prospects for further studies of thermally activated processes in the conditions of application of a high DC magnetic field are indicated.

“…Recent progress in design and construction of cryofree powerful high field magnets generating DC magnetic fields of 10-20 T and higher has led to an increased research interest in the study of the effects thermal processing in high magnetic fields on microstructure evolution and the related changes caused of physical properties [11]. In this work, the influence of annealing in magnetic field of 14 T on the development of structure, texture as well as soft magnetic properties in NO FeSi electrotechnical strips has been investigated.…”

In this work, we report on the effects of high static magnetic field on the formation of desirable crystallographic orientation of grains ("rotating" cube) during the primary recrystallization of non-oriented steels. Vacuum degassed non-oriented steel with the silicon content about 1 wt% was taken from industrial line after final cold rolling with 80% of deformation and then it was subjected to the laboratory annealing at temperature of primary recrystallization. Whole annealing process was carried with and without the applied external magnetic field of 14 T. The analysis of crystallographic orientation of experimental material was studied by electron backscattered diffraction technique. The microstructural and textural observations have shown a small difference in average grain size between samples annealed with and without magnetic field as well as increase of the "rotating" Cube component and decrease of the intensity of deformation texture by application of magnetic field. The magnetic measurements show that the coercivity value of the sample annealed in the magnetic field of 14 T can be reduced by approximately 3% in comparison with sample annealed under the zero field conditions.
