Effect of cold-rolling on the crystallization behavior of amorphous Al88Y7Fe5 alloy

As an alternative to rapid solidification processing, deformation processing offers new opportunities for the synthesis and modification of metastable phases. In one example, the crystallization behavior of amorphous Al-alloys can be modified by cold-rolling of melt-spun ribbons. An examination of cold-rolled Al88Y7Fe5 ribbons highlights the effect of rolling on the as-spun alloy as well as on the crystallization behavior during annealing. TEM-based particle size distribution measurements are used in conjunction with DSC measurements as a first step to analyze the deformation influence on the crystallization kinetics.
