研究了具有扩展塑性的zr基大块金属玻璃在弯曲作用下剪切带的发育及其间距随弯曲角度的变化规律。研究发现，现有剪切带的滑动是塑性大块金属玻璃塑性变形的重要机制。研究结果有助于理解金属玻璃的变形。
Shear band development and evolution of their spacing under bending in a Zr-based bulk metallic glass with extended plasticity has been monitored as a function of bending angle from the onset of plastic deformation to fracture. We find that sliding of existing shear bands is an important mechanism accounting for the plastic deformation of the plastic bulk metallic glass. The results are beneficial to understanding deformation in metallic glasses.
