Abstract
This study examines the fundamental issue of whether an elastic shear stress imposed on amorphous alloys causes structural changes during quasistatic loading. In order to deliver 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.
