Electron-beam-assisted superplastic shaping of nanoscale amorphous silica

By Kun Zheng, Chengcai Wang, Yong-Qiang Cheng, Yonghai Yue, Xiaodong Han, Ze Zhang, Zhiwei Shan, Scott X Mao, Miaomiao Ye, Yadong Yin and Evan Ma


At room temperature, glasses are known to be brittle and fracture upon deformation. Zheng et al. show that, by exposing amorphous silica nanostructures to a low-intensity electron beam, it is possible to achieve dramatic shape changes, including a superplastic elongation of 200% for nanowires
