Abstract
Amorphous alloys having high strength, high hardness, high crystallization temperature, high saturation magnetic induction, low coercive force, high magnetic permeability and particularly low deterioration of magnetic properties with lapse of time, have a composition formula of EQU T.sub.a X.sub.b Z.sub.c or T.sub.a' X.sub.b' Z.sub.c' M.sub.d, wherein PA1 T is at least one of Fe, Co and Ni, PA1 X is at least one of Zr, Ti, Hf and Y, PA1 Z is at least one of B, C, Si, Al, Ge, Bi, S and P, PA1 a is 70-98 atomic %, PA1 b is not more than 30 atomic %, PA1 c is not more than 15 atomic %, PA1 sum of a, b and c is 100 atomic %, PA1 M is at least one Mo, Cr, W, V, Nb, Ta, Cu, Mn, Zn, Sb, Sn, Be, Mg, Pd, Pt, Ru, Os, Rh, Ir, Ce, La, Pr, Nd, Sm, Eu, Gd, Tb and Dy, PA1 a' is 70-98 atomic %, PA1 b' is not more than 30 atomic %, PA1 c' is not more than 15 atomic %, PA1 d is not more than 20 atomic %, and PA1 sum of a', b', c' and d is 100 atomic %.
