Plasticity improvement of a bulk amorphous alloy based on its viscoelastic nature. |
| 초록 |
This study examined the fundamental issue of whether an elastic shear stress imposed on an amorphous alloy causes structural changes during the process of quasistatic loading. In order to deliver the elastic shear stress to the workpieces, a quasistatic shear deforming device was designed. With repeated application of elastic shear stress, the plasticity of the shear-deformed amorphous alloys increased, while the yield strength decreased. These behaviors were analyzed from the perspective of the structural changes associated with the viscoelastic nature of amorphous alloys. |
