In-situ TEM experiments demonstrate large plasticity in pure magnesium mediated by pyramidal dislocations

With the support by the National Natural Science Foundation of China,the research team led by Prof.Shan ZhiWei(单智伟)at the Center for Advancing Materials Performance from the Nanoscale(CAMPNano),State Key Laboratory for Mechanical Behavior of Materials,Xi'an Jiaotong University,clarified the controversies regarding pyramidal dislocations that are critical to understanding the ductility of magnesium,which was published in Science(2019,365:73-75).
