Slip in directionally solidified Mo-alloy micropillars-Part II: Pillars containing defects

In situ Laue analysis during microcompression is carried out on Mo-alloy pillars containing defects due to focused ion beam milling or pre-strain. Independently of how the defects are introduced, if the diffraction peaks are streaked prior to deformation, slip starts in the direction matching the observed streaking, even if this corresponds to a low Schmid factor. The amount of pre-strain influences the deformation behaviour in terms of hardening and strain bursts. (C) 2012 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
