Abstract
Disclosed are an amorphous alloy, a manufacturing method thereof, and a product including the same. The novel amorphous alloy according to an embodiment includes a quaternary amorphous alloy matrix including Zr, Ni, Cu, and Al; and a complex concentrated alloy (CCA) dispersed inside the quaternary amorphous alloy matrix and including at least two elements selected from Ti, Zr, Hf, V, Nb, Ta, and Mo.
Claims22
