“…In these cases, the particle assembly was governed by the applied magnetic force, magnetic dipole-dipole interactions, and chain-chain interaction. Recently, Liu et al extended this research to other binary and multi-alloy systems, such as Bi-11.8 wt.%Mn 72) and Al-12Si-11.8Mg-6.5Ti., 73) respectively. During the solidification of Bi-11.8 wt.%Mn alloys in high gradients, there are three typical structures, i.e., primary MnBi, primary Mn and MnBi/Bi eutectic in the alloys whereas for Al-12Si-11.8Mg-6.5Ti alloys, there are five typical structures, i.e., Mg2Si, (Al,Si)3Ti, (Al,Si)3Ti-Ti5Si4 coupled phase, Al/Mg2Si eutectic and Al/Si eutectic in the alloys.…”
