Patent ID: 7794553

Claim:
A thermoplastically processable bulk solidifying amorphous alloy having a composition in accordance with the equation: (Zr x Ti (1-x) ) a1 ETM a2 Cu b1 LTM b2 Be c , where (ETM) comprises the group of Early Transition Metals, (LTM) comprises the group of Late Transition Metals; where x is an atomic fraction and a1, a2, b1, b2, and c are atomic percentages, and where (a1+a2) falls within the range of 60 to 80%, x is in the range of 0.05 to 0.95, (b1+b2) is in the range of 2 to 17.5%, c is at least 15%, and Ni comprises no greater than 5% of the overall composition; and where the alloy has a supercooled liquid region (ΔT) defined as the temperature difference between the glass transition temperature and crystallization temperature of the alloy of at least 135 K and a viscosity within this supercooled liquid region that falls below a value of less than about 10 5 Pa-s when measured at a heating rate of 20 K/min.
