Mechanical properties of cold‐rolled Zr60Ti5Ag5Cu12.5Ni10Al7.5 metallic glass

In this work, the effect of cold‐rolling on the mechanical behavior of the Zr60Ti5Ag5Cu12.5Ni10Al7.5 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.
