<p>INVENTION: IRON GROUP TRANSITION METAL-REFRACTORY METAL-BORON GLASSY ALLOYS INVENTOR: RANJAN RAY Low boron content alloys containing molybdenum are disclosed. The glassy alloys of the invention consist essentially of about 5 to 12 atom percent boron, one of the member selected from the group of 20 to 60 atom percent molybdenum and about 13 to 40 atom percent tungsten and the balance essentially one of the group consisting of cobalt, iron and nickel. The glassy alloys evidence hardness values of at least about 1000 Kg/mm2, ultimate tensile strengths of at least about 330 Kpsi and crystallization temperatures of at least about 445.degree.C. The high mechanical strength and high thermal stability of the glassy alloys of the invention render them suitable for use as reinforcement in composites for high temperature applications.</p> |
