Abstract

Cu/Zr-type multilayers prepared by cold-rolling have been subjected to cold and hot pressing until the onset of crystallization. It is found that application of a uniaxial stress perpendicular to the plane of the layer interfaces accelerates both the growth rate of amorphous interlayers and the onset of subsequent crystallization. These effects have been attributed to stress-induced flow parallel to the interfaces that helps relax diffusion-induced internal stresses and increases interfacial reaction constants controlling crystalline layer formation at the amorphous/Zr layer interfaces.
