Abstract
Amorphous samples of a multicomponent Zr-Al-Ni-Cu alloy have been synthesized at ambient temperature from a layered array of individual elemental sheets by repeated low-strain-rate cold rolling with intermediate folding. The alloying reactions during cold rolling were monitored with electron and X-ray diffraction and thermal analysis. During the initial stage of processing a dissolution of solute into Zr together with a reduction in grain size to about 30 nm was observed and with further processing a fully amorphous sample was obtained after 120 deformation cycles. The characteristics of the amorphous phase developed by repeated cold deformation indicate that it is compositionally homogeneous, structurally relaxed and without the typical impurity levels obtained by mechanical alloying.
