| FeCoNbB Hitperm, where 4 at% of Fe are substituted by V or Cr show expected reduction of saturation, slightly lowered magnetostriction and slightly higher coercivity. Despite of significantly larger grain caused by Cr, the coercivity does not increase sharply. Detrimental ambient influences at non-vacuum annealing are not appreciably blocked by V or Cr. |
