“…Compared to the imposed alternating MF (electromagnetic stirring) or pulsed MF on the ESR process proposed by other researchers [36,37], because skin effect (due to the water-cooled mold) tends to happen with the application of alternating or cyclic MF, there is a significant benefit for static MF. Such technology is currently being investigated for a variety of steel grades including low-alloyed GCr15 bearing steel [38,39], medium-alloyed H13 die steel [40,41], and high-alloyed M2 HSS [42,43]. Guo et al [42,43] applied a transverse static MF (TSMF, with different magnetic flux densities) for regulating M2 HSS solidification upon ESR.…”

The depth of the metal pool in the ESR ingot decreased after applying the TSMF, and the coarse net-like morphology of the ECs almost disappeared.…”

This study investigates the influence of a superimposed axial static magnetic field (ASMF) on the morphology of metal pool and eutectic carbides (ECs) in electroslag remelted M2 high-speed steel (HSS). The application of ASMF caused the metal pool to become shallower, and the solidified structure to expand axially, along with finer (i.e., more uniformly distributed and crystallographically oriented) ECs. Lorentz force-driven unidirectional circulation in slag pool was the primary cause of the metal pool’s morphological adjustment; this resulted in a more homogenous temperature distribution in slag pool. Thus, the heat transfer from the slag pool to the metal pool became more uniform, creating a metal pool that is shallower. Additionally, local solidification time (LST) became shorter, while the number of (Ti, V)N-Al2O3 inclusions serving as heterogeneous nuclei for EC formation increased due to ASMF, enabling finer EC with more crystallographic orientations in ESR ingots.

“…Indeed, the crystal orientation is considered to be influenced by the SMF in both thermodynamic and kinetic ways. In the past decade, our group has systematically investigated the role of SMFs in the solidification process, including atomic diffusion [55,56,66,67], dendrite growth [61,68], homogenization of the secondary phase in immiscible alloy [69][70][71], and electroslag remelting in steel [72][73][74]. Based on these studies, we suggested that ETA materials processing under an SMF holds promise for both fundamental scientific research and industrial applications.…”

Processing metallic alloys under a static magnetic field (SMF) has garnered significant attention over the past few decades. SMFs can influence both the thermodynamics and kinetics of the solidification process by introducing extra force and energy. Eutectic-type alloys (ETAs) are commonly used as research materials under SMFs due to their featured microstructures. This review aims to present theoretical and experimental results regarding ETAs under SMFs, from post-analysis to in situ observation, to demonstrate the effects of magnetic phenomena such as magnetic braking, thermoelectric magnetic convection, magnetic gradient force, and magnetic energy on the thermodynamics and kinetics of microstructural evolution. In this paper, we adopt a hybrid approach between a review and an overview to comprehensively examine the effect of SMFs on the solidification process. Firstly, we provided a concise review of the historical research on the SMF’s impact on solidification in the literature. Next, we elucidated the basic physical principles of an SMF in material processing, followed by an introduction of numerous laboratory and industrial experiments that have utilized SMFs. Finally, we summarized the effects of SMFs on solidification in the past and provide insights into future research directions.
