Crystallization of amorphous CuZr2

Abstract
X-ray and electrical-resistance studies on amorphous CuZr2 show this system to crystallize by a polymorphous transformation directly to the body-centered-tetragonal crystal with no intervening stages. The transformation is excellently described by a Johnson-Mehl—type equation with the kinetics controlled by diffusion with a constant rate of nucleation. The amorphous phase is metastable with an activation energy of 3.26±0.10 eV.
