High speed imaging is combined with high strain rate loading to probe the evolution of strain localization leading up to failure in Mg alloys. From this study pathways for deformation are identified which lead to undesired shear band formation and crack formation. Show below is a comparison of the strain localization that occurs at a […]

Using infra-red thermography and selected orientations, high strain rate loading is used to evaluate the conversion of plastic work to heat for specific deformation processes in magnesium alloy AZ31B. Mechanisms are approached through studying orientations that accommodate deformation through one of the following mechanisms to the greatest extent possible: 1) basal, 2) non-basal, and 3) […]

As the microstructure of a material is refined from the micron scale to the nanoscale there is a significant increase in the interface density of the material. If the density of interfaces is high enough, the macroscopic deformation response can be influenced by the structure of the interface at the nanoscale. Shown below is a […]
