  • space="preserve" listing-type="equation">(Zr.sub.1-zx Ti.sub.x).sub.a1 ETM.sub.a2 (Cu.sub.1-y Ni.sub.y).sub.b1 LTM.sub.b2 Be.sub.c
where x and y are atomic fractions, and a1, a2, b1, b2, and c are atomic percentages, wherein;

ETM is at least one early transition metal selected from the group consisting of V, Nb, Hf, and Cr, wherein the atomic percentage of Cr is no more than 0.2a1;

LTM is a late transition metal selected from the group consisting of Fe, Co, Mn, Ru, Ag and Pd;

a2 is in the range of from 0 to 0.4a1;

x is in the range of from 0 to 0.4; and

y is in the range of from 0 to 1; and

(A) when x is in the range of from 0 to 0.15;

(a1+a2) is in the range of from 30 to 75%,(b1+b2) is in the range of from 5 to 52%,b2 is in the range of from 0 to 25%, andc is in the range of from 6 to 47%;

(B) when x is in the range of from 0.15 to 0.4;

(a1+a2) is in the range of from 30 to 75%,(b1+b2) is in the range of from 5 to 52%,b2 is in the range of from 0 to 25%, andc is in the range of from 5 to 47%.
