Nanosized Cu-Li glass

Amorphous metallic alloy (also known as metallic glass) was firstly discovered in the 1960s as a‘‘young"member of the amorphous material family [1]. Their unique metastable disordered structure imparts metallic glasses many fascinating properties and features such as high elasticity and high strength, excellent wave-absorption ability and ultralow elastic moduli [2,3]. In general, the formation of an amorphous alloying phase requires a relatively large negative heat of mixing between the constituent
