Abstract

The orientation spread in an aluminum bicrystal was predicted using a DIC-based Taylor model during plane strain compression up to a strain of 5%. The modified Taylor model was integrated with a digital image correlation (DIC) technique, with the aid of which the micro-strain behavior of the bicrystal was investigated, using an experimental approach on one hand and, on the other hand, the strain components determined by DIC were computed for the local orientation rotation together with a Taylor model. It was observed that the higher crystal deforms more than the low crystal. The orientation spread predicted using the modified Taylor model shows a similar trend as that measured by EBSD for the higher crystal, but the spread direction of the low crystal was not correctly predicted using the DIC-based Taylor model.
