Roles of Nanoclusters in Shear Banding and Plastic Deformation of Bulk Metallic Glasses.

摘要

During the course of this research we published 33 papers in various physics/material journals. Shear banding is associated with a local viscosity drop, which may be associated with a temperature rise in the shear band or dynamic stability caused by excessive applied stress. Molecular dynamic simulations recently have shown that applied stress and temperature are equivalent and shear banding is essentially a stress-induced glass transition process.
