How to manufacture a tape from an alloy, a magnetic core, and an alloy

Japanese Patent JP6040429

B2

Provision is made of an alloy consisting of Fe100-a-b-c-d-x-y-zCuaNbbMcTdSixByZz and up to 1 atom% impurities, where M is one or more of the elements Mo, Ta or Zr, T is one or more of the elements V, Mn, Cr, Co or Ni and Z is one or more of the elements C, P or Ge, and 0 atom% = a < 1.5 atom%, 0 atom% = b < 2 atom%, 0 atom% = (b+c) < 2 atom%, 0 atom% = d < 5 atom%, 10 atom% < x < 18 atom%, 5 atom% < y < 11 atom% and 0 atom% = z < 2 atom%. The alloy is in the form of a strip and has a nanocrystalline microstructure, in which at least 50% by volume of the grains have a mean size of smaller than 100 nm, a hysteresis loop with a central linear part, a remanence ratio, Jr/Js, c, to anisotropy field strength, Ha, < 10%.
