Soft magnetic alloy ribbons Fe81Si4B12-xP2Cu1Mx ( M = Cr, Mn and V; x = 0, 1, 2, 3) were prepared by the single roller melt spinning method. The effects of Cr, Mn and V substitution for B on the glass forming ability, microstructure and magnetic properties were investigated. Partial substitution of B by Cr or Mn decreases the glass forming ability of this alloy system, while proper substitution by V effectively improves the glass forming ability, widens the temperature interval between two crystallization onset temperatures and optimizes the soft magnetic properties of this alloy system. The Fe81Si4B10P2Cu1V2 alloy annealed at 425 degrees C for 10 min shows excellent magnetic properties with low coercivity H-c of 8.1 A/m, high magnetic flux density B-8000 of about 1.72 T. Good glass forming ability, large temperature interval between two crystallization onset temperatures and excellent magnetic properties make this alloy a promising candidate for future industrial application.
