Abstract

The elastic deformation behaviors of bulk amorphous alloys during elastostatic compression were examined. Depending on the alloy deformation characteristics, the elasticity of amorphous alloys consists of strain components characterized by ideal elasticity, anelasticity, and viscoelasticity. The strain component associated with viscoelasticity is irreversible and causes the generation of excess free volume, which in turn alters the mechanical properties. This article discusses how the properties of amorphous alloys can be altered by the application of elastostatic compression.
