Original Abstract Submitted
The present invention provides an undercooling solidification method for preparing an amorphous or nanocrystalline soft magnetic alloy with high Fe content and the applicable amorphous or nanocrystalline alloy composition. The undercooling solidification is realized by glass purification combined with cyclical superheating or electromagnetic levitation melting. An undercooling solidification alloy is prepared into amorphous strips or powders through rapid quenching or atomization of melt, and can be prepared into a nanocrystalline alloy through heat treatment. The chemical formula of the applicable amorphous or nanocrystalline alloy is FeSiBM, wherein M is one or more of P, C, Nb, Mo, Zr, Hf, Mo, Y, Cu and Co. The amorphous or nanocrystalline alloy prepared by undercooling non-equilibrium solidification has the characteristics of high amorphous forming ability, high saturation magnetization and low coercive force.
