Abstract
A class of amorphous metal alloys is provided in which the alloys are rich in iron, nickel, cobalt, chromium and/or manganese. These alloys contain at least one element from each of three groups of elements and are low in metalloids compared to previously known liquid quenched amorphous alloys rich in iron, nickel, cobalt, chromium and/or manganese. The alloys can be readily formed in the amorphous state and are characterized by high hardness, high elastic limit and, for selected compositions, good corrosion resistance. Products made from these alloys include cutting tools, such as razor blades.
