Nickel-free zirconium and / or hafnium-based bulk amorphous alloys

摘要

A solid nickel-free amorphous alloy consisting of: - a zirconium or hafnium base, constituting the balance, with a total zirconium and hafnium of not less than 52.0 and not more than 62.0; - copper: not less than 16.0 but not more than 28.0; - iron: greater than or equal to 0.5 and less than or equal to 10.0; - aluminum: not less than 7.0 but not more than 13.0; At least two filler metals (X) taken from the family comprising Ti, V, Nb, Y, Cr, Mo, Co, Sn, Zn, P, Pd, Ag, Ir, Os, and Hf when said base does not include them, and Zr when said base does not include said atomic atomic percentage of said filler metals being greater than or equal to 6.0 and less than or equal to 10.0.
