- High-resolution back-scattered diffraction provides a tool to measure strains in metals and alloys. This paper highlights for the first time an iterative process required to obtain valid high-angular resolution data in polycrystals by employing a crystal plasticity approach to account for the fact that highly deformed grains do not contain a zero reference point. This insight in important and not previously considered; this paper shows the balance needed between modelling and experimental validation not only for materials behaviour but to develop robust lifing models for industry.
