VISCOELASTIC RELAXATION OF BULK METAL GLASS Zr46.75Ti8.25Cu7.5Ni10Be27.5AT HIGH TEMPERATURE

摘要：

The internal friction of the bulk metallic glass (BMG) Zr46 75Ti8.25Cu7 5NiioBe27.5 (at.％) originates from the viscoelasticity.The viscoelastic internal friction increases with decreasing vibration frequency at higher temperatures and increases with increasing frequency at lower temperatures.It gives rise to a minimum as a function of frequency.The proposed viscoelastic relaxation three-parameter model can be used to describe the viscoelastic internal friction of the present BMG.
