Two similarly oriented grains are studied after 9% tension with 3DXRD and modelling.

The measured spatial orientation spread is qualitatively predicted using the ALAMEL model.

Shear at grain boundaries is identified as the dominant grain interaction mechanism.

The same slip systems operate throughout each grain, but with different relative activities.
