Grain refinement in Fe-rich FeSiB(P)NbCu nanocomposite alloys through P compositional modulation

•P addition in FeSiB(P)NbCu melt-spun alloys promotes α-Fe grain refinement.•Solute partition forms core–shell like glassy region around α-Fe nanocrystal.•P segregation increases α-Fe growth activation energy and inhibits grain growth.•4 at% P alloy shows optimal properties with D
