Ranjan Ray: Ultra-high strength glassy alloys. Allied Chemical Corporation, Ernest D Buff, February 20, 1979: US04140525 (4 worldwide citation)

Several iron-base glassy alloys in the Fe-Cr-Mo-B system have very high tensile strengths, ranging from about 550 to 700 Kpsi. These alloys consist essentially of about 56 to 68 atom percent iron, about 4 to 9 atom percent chromium, about 1 to 6 atom percent molybdenum and about 27 to 29 atom percen ...
