Amorphous metal alloy for structural reinforcement

Metal alloy that is primarily glassy, has improved ultimate tensile strength, bend ductility, resistance to thermal embrittlement and resistance to corrosion and stress corrosion, said alloy having a composition defined by the formula Fe.sub.a Cr.sub.b C.sub.c P.sub.d Mo.sub.e W.sub.f Cu.sub.g B.sub.h Si.sub.i where

• "a" ranges from about 61 to 75 atom percent,
• "b" ranges from about 6 to 10 atom percent,
• "c" ranges from about 11 to 16 atom percent,
• "d" ranges from about 4 to 10 atom percent,
• "e" ranges from about 0 to 4 atom percent,
• "f" ranges from about 0 to 0.5 atom percent,
• "g" ranges from about 0 to 1 atom percent,
• "h" ranges from about 0 to 4 atom percent, and
• "i" ranges from about 0-2 atom percent,
• with the proviso that the sum [c+d+h+i] ranges from 19 to 24 atom percent and the fraction [c/(c+d+h+i)] is less than about 0.84.
