In-Situ TEM Observation of Twinning and Detwinning During Cyclic Loading in Mg

In-situ transmission electron microscopy (TEM) is used to directly observe twin evolution in Mg under tension and compression. Twins grow during tensile loading. Upon load reversal, the first-generation twin detwins by nucleation and growth of a second-generation twin within its volume. This mechani...
