We present the first molecular-dynamics study of the amorphization of a crystalline alloy (NiZr/sub 2/) induced by chemical disorder. We used a n-body potential in conjunction with isobaric-isothermal molecular dynamics. The behavior of the pair distribution function suggests that the instability leading to the amorphous state is a first-order phase transformation.
