      Crystallization behaviour and magnetic properties of melt-spun Fe–Si–B–Nb–Cu alloys have been investigated. It is found that the primary phase changes from 𝛼-Fe(Si) to Fe3Si (DO3) on increasing the Si content. The coercivity of the alloys containing the Fe3Si phase is significantly lower as compared to the alloy containing 𝛼-Fe(Si) phase. A heat treatment temperature–time–coercivity map has been obtained for optimization of the coercivity.
