ABSTRACT:
Glassy iron, nickel and cobalt rich alloys that contain at least one of molybdenum, tungsten, titanium, chronium and vanadium, together with low boron content, are disclosed. The alloys consist essentially of about 3 to 10 atom percent boron, about 3 to 25 atom percent of at least one member selected from the group consisting of molybdenum, tungsten, titanium, chromium and vanadium, and about 72 to 86 atom percent of at least one member selected from the group consisting of iron, nickel, cobalt and manganese. The glassy alloys are readily formed in the amorphous state and are characterized by high hardness, high yield strengths and excellent thermal stability.
