Popis:	We examine the size effect and strengthening mechanisms of bcc iron pillars. The single-crystal pillars were machined with focused ion beam and tested with a nanoindentation device with the compression axis along the crystallographic direction. We compare our test results with both older literature on whiskers and micro/macro specimens, and recent results from atomistic modelling. We find that the obtained results can be explained on the basis of current theories based on small-scale plasticity.
