Description

An n-body potential is constructed and applied to investigate the crystal-to-amorphous transition of the immiscible Cu-Nb system by molecular dynamics simulation. It is found that supersaturated solid solutions could turn into disordered states when the composition falls into the range of about 15-72 at.% Nb, suggesting that amorphous alloy could be formed in this range for the Cu-Nb system. Interestingly, amorphous phases are obtained in the Cu70Nb30 and Cu30Nb70 multilayered films upon ion beam mixing
