Effects of sintering temperature on microstructure and property evolution of Fe81Cu2Nb3Si14 soft magnetic materials fabricated from amorphous melt-spun ribbons by spark plasma sintering technique

► Fe81Cu2Nb3Si14 amorphous powders were prepared by ball milling of melt-spun ribbons. ► The processing-microstructure-property relationships have been systemically investigated. ► The SPS samples have a large size as well as a high relative density. ► The best soft magnetic prosperity of the sintered samples was achieved at 630 °C.
