Abstract
A metallic glass formed of an alloy including: (a-c-x) atomic % of Ni, with a between 54 and 72; (b-y) atomic % of Nb, with b between 35 and 44; c atomic % of Cu, with c from 0.05 to 9; x atomic % of at least one element chosen from: Co, Fe, Ag, Mn, Pd, Au, Ir, Os, Pt, Re, Rh, Ru and Te, with x from 0 to 20; y atomic % of at least one element chosen from: Hf, Ta, Ti, Cr, Mo, Sc, V, W and Y, with y from 0 to 20; z atomic % of at least one element chosen from: B, Si, Al, Sn, Ca, Ga, In, Mg and Zn, with z from 0 to 10; at most 3 atomic % of Zr; and other elements at most 0.1% by weight each and at most 0.5% by weight in total.
