| Abstract Scope |
In heavily twinning Magnesium AZ31, in situ investigation of crystallite-scale strain patterns with microscopic digital image correlation (DIC) leads to intriguing results at the onset of the twin plateau. These include intense strain heterogeneity revealed at every length-scale in the form of banded patterns, a local explosion (rather than evolution) of plastic strain fields, and opposite sense microscale shear patterns existing inside a macroscopic shear band of a certain sense (Aydiner and Telemez, Int. J. Plas. 2014(56), p. 203). With a more advanced and higher-magnification microscopic scanning DIC setup developed in-house, the current study considers the effect of the crystallographic texture on the development, strain content and strain heterogeneity levels of these multi-scale patterns. This in situ parametric study will cover lightly-textured (cast), rolled and extruded AZ31 samples of comparable grain size. The samples, in addition, will be loaded in reverse to investigate detwinning and surrounding deformation structures. |
