Mechanical properties of cold‐rolled Zr 60 Ti 5 Ag 5 Cu 12.5 Ni 10 Al 7.5 metallic glass

In this work, the effect of cold‐rolling on the mechanical behavior of the Zr 60 Ti 5 Ag 5 Cu 12.5 Ni 10 Al 7.5 metallic glass has been investigated. The results reveal that cold‐rolling is very effective for improving the room temperature mechanical properties of the material. A small size reduction of only 5% remarkably improves the strength as well as the plastic deformation, which increase by about 20 and 40%, respectively, with respect to the as‐cast material. The origin of the enhanced mechanical properties is most likely due to the creation during cold‐rolling of a heterogenous microstructure consisting of shear softened regions surrounded by hard undeformed regions.
