Abstract:
A nanostructure material having a tensile yield strength from at least about 1.5 to about 2.3 GPa and a ductility of from at least about 1 to about 18 percent strain-to-failure,wherein the material consists essentially of about 0.003% to about 0.02% C, no more than about 0.10% Mn, no more than about 0.10% Si, no more than about 0.01% P, no more than about 0.003% S, no more than about 0.1% Cr, no more than about 0.2% Ni, no more than about 0.1% Mo, from about 48 to about 50% Co, from about 1.8 to about 2.2% V, from about 0.03 to about 0.5% Nb, no more than about 0.004% N, and no more than 0.006% O, and iron as the balance.
