摘要：

This study investigates the small-scale deformation behavior of [111], [2 10] and [00 1] NiTi shape memory alloys. In stark contrast to bulk deformation behavior, the pseudoelastic behavior of sub-micron diameter compression pillars is highly dependent on diameter and relatively independent of orientation. Transmission electron microscopy is used to investigate pillars post-compression, giving insight into the deformation mechanisms involved. (C) 2008 Acta Materialia Inc. Published by Elsevier Ltd.
