Abstract
Ni—Fe—Si—B and Ni—Fe—Si—B—P metallic glass forming alloys and metallic glasses are provided. Metallic glass rods with diameters of at least one, up to three millimeters, or more can be formed from the disclosed alloys. The disclosed metallic glasses demonstrate high yield strength combined with high corrosion resistance, while for a relatively high Fe contents the metallic glasses are ferromagnetic.
