Abstract Scope |
Accurate identification of active slip systems is fundamental for understanding and predicting deformation behavior in HCP metals. Trace analysis and, to a lesser extent, high-resolution digital image correlation (HRDIC), have been used to identify slip activity in various metals. One particular issue that arises when several potential slip systems are active involves the accurate alignment of EBSD and SEM data – small errors in orientation assignment can lead to significant ambiguity in the results. This study considers different registration techniques for reconciling the different maps, for improved slip system identification. Both trace analysis and HRDIC (using gold remodeling) are applied to Ti-6-4 that is deformed using simple tension, and the complex continuous bending under tension. These results are compared with HREBSD and XRD /CMWP estimates of active slips systems. Insights from the experimental campaign are compared with predictions from CPFE models. |
