Isothermal and non-isothermal differential scanning calorimetry experiments were carried out to study rapidly solidified Al90Fe5Ce5 alloy. Microstructural analysis suggests that icosahedral nanoparticles are homogeneously distributed in the matrix of annealed amorphous Al90Fe5Ce5 alloy. The presence and homogeneous distribution of icosahedral structure units and icosahedral short-range domains appear to be critical for the formation and stability of the amorphous phase.

Experiments to continuously separate Fe-Al-Zn dross phase from hot dip galvanising zinc melt were conducted on a laboratory scale apparatus by using high frequency alternating magnetic field. Effects of processing time (t) on separation efficiency were investigated. The experimental results show that using the electromagnetic repulsive force resulting from the electrical conductivity difference between zinc melt and Fe-Al-Zn dross phase, the deleterious zinc dross particles causing surface defects of galvanising steel sheets can be continuously separated from the zinc bath under alternating magnetic field, and the separation efficiency increases with the increase in processing time. When the magnetic frequency is 17?5 kHz, the effective magnetic flux intensity is 0?1 T, the cross-section of the ceramic square pipe is 10610 mm, and the processing time is 0?6-2?5 s, the separation efficiency of zinc dross varies from 43?76 to 85?71%, and the experimental results are in reasonable agreement with the theoretical results.
