Evolution of microstructure and magnetic properties during annealing of a Cu-doped Fe75.3C7.0-Si3.3B5.0P8.7Cu0.7 metallic glass were investigated via atom probe tomography. Cu segregation, which contains a rapid nucleation stage and a sluggish growth stage, was found to precede and may trigger the segregation of other elements and promote the following nanocrystallization. The nano-sized alpha-Fe precipitates have a composition close to that of the grain-orientated high-silicon steel, giving rise to the enhancement in the magnetization. (C) 2016 Elsevier B.V.
