“…In recent years, an important new technique called high magnetic field (HMF) processing has been applied to material processing as a non-contact method [12][13][14], especially during solidification [15,16], which contributes to the influencing of secondary particle migration/orientation [17] and liquid metal motion and convection [18,19] to achieve more accurate control over the microstructure of materials [20,21]. The development of superconductivity technology has made it easy to obtain HMF of 10 T and above, which has promoted the application of HMFs in materials science and engineering and is therefore regarded as a new opportunity in this field [22,23].…”

Immiscible alloy is a kind of functional metal material with broad application prospects in industry and electronic fields, which has aroused extensive attention in recent decades. In the solidification process of metallic material processing, various attractive phenomena can be realized by applying a high magnetic field (HMF), including the nucleation and growth of alloys and microstructure evolution, etc. The selectivity provided by Lorentz force, thermoelectric magnetic force, and magnetic force or a combination of magnetic field effects can effectively control the solidification process of the melt. Recent advances in the understanding of the development of immiscible alloys in the solidification microstructure induced by HMF are reviewed. In this review, the immiscible alloy systems are introduced and inspected, with the main focus on the relationship between the migration behavior of the phase and evolution of the solidification microstructure under HMF. Special attention is paid to the mechanism of microstructure evolution caused by the magnetic field and its influence on performance. The ability of HMF to overcome microstructural heterogeneity in the solidification process provides freedom to design and modify new functional immiscible materials with desired physical properties. This review aims to offer an overview of the latest progress in HMF processing of immiscible alloys.

“…The physical refinement method not only has a good refining effect but also can effectively homogenize the alloy melt temperature and solute distribution fields [18,19] . Both the refiners and vibrations can improve the solid solubility of the alloying elements in the α-Al matrix [20,21] . This increased solubility improves the mechanical properties of the as-cast and heat treated alloys [22,23] .…”

Al-Cu casting alloys have high strength, good machinability, and excellent heat resistance [1][2][3] . However, Al-Cu alloys usually contain coarse α-Al dendrites and inhomogeneous Al 2 Cu phases, resulting in poor mechanical properties [4,5] . Thus, grain refinement treatments are usually required to improve their microstructure and properties [6][7][8] . Chemical and physical methods are the main grain refining methods for Al alloys. The chemical refinement method, i.e., adding refiners into the alloy, is considered the most effective and practical in the Al processing industry owing to its advantages of fast refinement, convenient operation, and strong adaptability.
