Deformation-Induced Crystallization and Amorphization of Al-Based Metallic Glasses
Abstract
A main requirement for the application of nanostructured materials for structural applications is their thermal stability Structural materials are often exposed to mechanically-induced stress states Nanomaterials for structural applications should therefore retain their microstructure not only within a defined temperature range but also under applied load. Cold-rolling experiments with melt-spun Al87Ni10Ce3 ribbons containing a dispersion of nanocrystallites in an amorphous matrix demonstrate that during the continued deformation through repeated rolling and folding crystallization as well as amorphization reactions could be induced. The results indicate that in addition to the microstructure control through annealing of precursor materials, deformation processing represents an effective approach to the synthesis of amorphous and nanophase composite materials.
