Anisotropy in a bulk metallic glass induced by uni-directional heat flow
Source abstract
Abstract
Abstract In this work, a controlled uni-directional heat flow was realized during the bulk metallic glasses preparation by using a vertical Bridgman solidification apparatus. Fully amorphous Zr41.2Ti13.8Cu12.5Ni10Be22.5 bulk metallic glass specimens were prepared. The obvious difference in hardness between the cross and longitudinal sections of the as-prepared Zr41.2Ti13.8Cu12.5Ni10Be22.5 bulk metallic glass specimens was identified, indicating strong mechanical anisotropy. The observed anisotropy can be ascribed to the uni-directional heat flow during the process of Bridgman solidification. The mechanical anisotropy may be explained by the free volume theory.
