| Abstract Scope |
Magnesium (Mg) alloys have received tremendous attention over the last few decades for improving energy efficiency of various engineering fields. To achieve widespread applications, understanding the dynamic mechanical response of the Mg alloys at different strain rates becomes a crucial issue for judging their in-service performance. In the present work, the mechanical properties of the Mg alloys were investigated at moderate strain rates and high strain rates, respectively. Microstructure evolution was characterized by the in-situ EBSD technique and the dislocation density, including the fractions of dislocations with different Burgers vectors, was determined based on the synchrotron XRD data. The rate sensitivity of plastic deformation was studied. A different deformation mechanism at high strain rate is observed and possible mechanisms contributing to this effect are explored. |
