In-Situ Dynamic Investigation of Plastic Deformation Carriers in Magnesium and the Effects of Multifield

The processingProcessing of magnesium and its alloys, as well as the deformation and damage during service, are closely related to the behavior of plastic deformationPlastic deformation carriers, such as dislocationDislocation nucleationNucleation and slip, twinningTwinning formation and growth, interface formation and migration, and the interaction between various deformation carriers. Meanwhile, the behavior of these deformation carriers is also significantly influenced by alloying elements, precipitates, as well as various environmental factors involved in processing and service, such as high temperature, atmosphere, and electric fields. In this study, in-situ transmission electron microscopyIn-situ TEM with quantitative nanomechanical testing was employed to investigate the behavior of dislocationsDislocation, twins, and grain boundaries in magnesiumMagnesium, as well as their response to alloying elements, precipitates, temperature, hydrogen, and electric fields. The aim is to provide fundamental data for understanding of the deformation and damage mechanisms of magnesium and to contribute to the development of high-performance magnesium alloysMagnesium alloys (Mg alloys).
