Abstract

In order to obtain ductile bulk glassy alloys (BGAs) with macroscopic tensile elongation, cold rolling was examined using Zr50Cu30Ni10Al10 BGAs. Cold rolled structure is characterized by its unique fine-layered structure, which is composed of deformed band regions and non-deformed block regions. Since the deformed shear band region can be deformed lower shear stress than that of non-deformed region, cold rolled bulk glassy alloy can deform homogeneously. On the other hand, cold rolling ability is also important factor to fabricate the cold rolled glassy alloys with sufficient reproducibility. Density, which strongly influences on the mechanical properties of cast BGAs, is used to estimate the cold rolling ability. As the result, we can achieve the cold rolled ductile Zr50Cu30Ni10 Al10 BGA exhibiting significant tensile elongation.
