Abstract

Metallic alloys are disclosed containing Fe at 48.0 to 81.0 atomic percent, B at 2.0 to 8.0 atomic percent, Si at 4.0 to 14.0 atomic percent, and at least one or more of Cu, Mn or Ni, wherein the Cu is present at 0.1 to 6.0 atomic percent, Mn is present at 0.1 to 21.0 atomic percent and Ni is present at 0.1 to 16.0 atomic percent. The alloys may be heated at temperatures of 200° C. to 850° C. for a time period of up to 1 hour and upon cooling there is no eutectoid transformation. The alloys may then be formed into a selected shape.
