Enhancing tensile ductility of porous metallic glasses through shear band path design
Source abstract
Abstract
Enhancing the toughness of metallic glasses has consistently been a significant area of research. In this study, the influence of shear band paths on the properties of porous metallic glasses is thoroughly investigated using finite element simulations. The research uncovers the preferred path selection for shear band propagation in diverse heterostructures of porous metallic glasses. The findings reveal that shear bands predominantly propagate along paths where the angles formed by the first or second adjacent pores are in closer proximity to the direction of the maximum shear stress. Leveraging an extensive comprehension of the deformation mechanism of porous metallic glasses, the study proposes a hexagonal pore structure that exhibits exceptional tensile ductility. These outcomes offer valuable insights and design strategies for the engineering of porous metallic glasses in diverse applications.
