A bulk glassy Cu-Zr-Ti-Sn alloy with superior plasticity

Abstract

(Cu0.5Zr0.425Ti0.075)99Sn1 bulk glassy alloy exhibited a large plastic strain to failure, about 8%, in uniaxial compression. High resolution transmission electron microscopy showed formation of nanocrystallites in the sample subjected to a plastic strain of about 3%. The large plasticity was attributed to the deformation-induced nanocrystalization in an amorphous phase. © 2005 The Japan Institute of Metals.
