Characterization of deformation-induced structural change of Pd78Cu6Si16 metallic glass using a micro-sized cantilever-beam specimen

This paper reports an investigation of deformation-induced structural changes of Pd78Cu6Si16 metallic glass observed after the exact positions of the shear bands were identified. The propagation of shear bands induced nanocrystallization not inside the shear bands, but around them. We conclude that the nanocrystal formation results from the accumulating temperature rise caused by the propagation of numerous shear bands. The extremely large temperature rise inside the shear bands may have led to the re-formation of an amorphous structure. (C) 2009 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
