| Abstract: | In this work, the effect of channel‐die compression (CDC) on the mechanical behavior of the Zr41.2Ti13.8Cu12.5Ni10Be22.5 bulk metallic glass is analyzed. The results indicate that CDC can be successfully used as a pre‐deformation process to effectively enhance the room temperature plastic strain ability of metallic glasses. The origin of the improved mechanical properties is most likely due to the creation during CDC of a heterogenous microstructure consisting of hard and soft regions able to hinder the rapid propagation of shear bands. |
