Based on the fundamental physical principles that govern the effect of magnetic fields on the solidification of ETAs, this paper provides a comprehensive review of the impact of SMFs on microstructure thermodynamics and kinetics under various solidification conditions.…”

“…These well-known contactless forces and energy effects deepen our understanding of controlling the solidified microstructure using SMF and offer promising applications in the industrial area. To investigate the effect of a high SMF on the solidification process of ETAs, various master alloys, such as Al-Cu [14][15][16][17], Nb-Fe [18], Cu-Ag [19,20], Al-Si [21][22][23], Al-Mg [24], Al-Fe [25][26][27][28], Al-Ni [29], Al-Zn [30], Sn-Bi [31][32][33], Pb-Sn [34][35][36], Zn-Mg [37,38], Mg-Nd [39], Co-B [40,41], Co-Sn [42], Mn-Sb [43], Bi-Mn [44], Al-Si-Fe [45], Al-Cu-Ag [46], Al-Cu-Si [47], and NiAl-Cr(Mo)-Hf [48] have been selected for investigation and the research contents are listed in Table 1. During the investigation of solidification of ETAs under the SMF, the solidification theories under the SMF were gradually established.…”
