Abstract

In situ white beam Laue diffraction experiments on focused ion beam machined single crystal 10 μm Ni pillars are performed to explore the relation between the initial and evolving microstructures and the subsequent flow response. The pillar has a flow stress that is at least in the upper bound of the scatter of the flow stresses obtained for similar Ni pillars. Detailed analysis of the Laue pattern suggests that the strength is in part due to the low angle grain boundary acting as a dislocation barrier.
