Bragg coherent diffraction imaging of dislocation evolution in annealed Pt particles

We will use Bragg coherent diffraction imaging to image the mobility of dislocations inside Pt particles during annealing at up to 850°C. Dislocations have been inserted by nano-indentation prior to the experiment.

我们将采用布拉格相干衍射成像（Bragg coherent diffraction imaging）技术，对最高850℃退火过程中铂颗粒内部的位错迁移行为进行成像表征。实验前已通过纳米压痕法引入位错。
