Abstract

Al85Ce8Ni5Co2 metallic glass ribbon was devitrified by heat treatments just below its glass transition temperature and by severe plastic deformation applying ball milling and high pressure torsion. Evolution of the microstructure, thermal stability and further thermal history were compared for the different devitrification processes. Based on this mapping of phase selection processes, microstructural changes can be predicted for high temperature and/or high stress compaction which are often required for application of this light weight alloy.
