Shear Band Formation in Bulk Metallic Glasses
In recent times, there has been a growing interest in the machining of amorphous metallic alloys, which are also called bulk metallic glasses (BMGs). These materials differ from common polycrystalline metallic alloys, because their atoms do not assemble on a crystalline lattice, and as a result, they have unique physical, mechanical, and chemical properties. A number of BMGs have been found to ...
متن کاملModeling the Dynamic Propagation of Shear Bands in Bulk Metallic Glasses
A model is developed for quantifying shear-band propagation in bulk metallic glasses. This model is written in terms of the stress, temperature, and band propagation speed. The model quantifies the shear-band length, width, and speed, as well as the direction of propagation and the magnitude of displacement across the band. Corresponding author: B.J. Edwards, [email protected] (865) 9...
متن کاملEffective temperature dynamics of shear bands in metallic glasses.
We study the plastic deformation of bulk metallic glasses with shear transformation zone (STZ) theory, a physical model for plasticity in amorphous systems, and compare it with experimental data. In STZ theory, plastic deformation occurs when localized regions rearrange due to applied stress and the density of these regions is determined by a dynamically evolving effective disorder temperature....
متن کاملEvolution of shear bands in bulk metallic glasses under dynamic loading
Shear band spacing in Zr-based bulk metallic glasses (BMGs) under dynamic loads is found to vary with position and local strain rate in the indented region. To investigate the dependence of shear band evolution characteristics on local strain rate and normal stress, a micromechanical model based on momentum diffusion is proposed. The thermomechanical model takes into account the normal stress d...
متن کاملFracture behaviors under pure shear loading in bulk metallic glasses
Pure shear fracture test, as a special mechanical means, had been carried out extensively to obtain the critical information for traditional metallic crystalline materials and rocks, such as the intrinsic deformation behavior and fracture mechanism. However, for bulk metallic glasses (BMGs), the pure shear fracture behaviors have not been investigated systematically due to the lack of a suitabl...
