The presence of micro-texture regions (MTR) was characterized using polarized light microscopy (PLM) and correlated with electron backscatter diffraction (EBSD). The MTR morphology was observed to be pancake shape. The rolled block was predominant in <0001> MTR along the transverse direction (TD) and <10-10> MTR along the rolling direction (RD). Small-scale cantilever samples were fabricated along the three orientations. The effect of different variants of MTR was captured via bending creep at room temperature using digital image correlation (DIC). Tension-compression asymmetry was observed when cantilevers were loaded along RD. Asymmetry in creep behavior was attributed to the presence of MTR. A novel method of augmenting PLM and EBSD with precise strain mapping using DIC was established for MTR. This high-throughput testing method is a potential candidate for a more accurate prediction of mechanical behavior for aerospace applications.
