ABSTRACT:
An amorphous metal alloy has 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 61-75 atom percent, "b" ranges from about 6-10 atom percent, "c" ranges from about 11-16 atom percent, "d" ranges from about 4-10 atom percent, "e" ranges from about 0-4 atom percent, "f" ranges from about 0-0.5 atom percent, "g" ranges from about 0-1 atom percent, "h" ranges from about 0-4 atom percent and "i" ranges from about 0-2 atom percent, with the proviso that the sum [c+d+h+i] ranges from 19-24 atom percent and the fraction [c/(c+d+h+i)] is less than about 0.84. The alloy is economical to make, strong, ductile, and resists corrosion, stress corrosion and thermal embrittlement.
