本文研究了[111]、[210]和[001]NiTi形状记忆合金的小尺度变形行为。与体变形行为形成鲜明对比的是，亚微米直径压缩柱的伪弹性行为高度依赖于直径，相对独立于取向。透射电子显微镜用于调查柱压缩后，深入了解所涉及的变形机制。
This study investigates the small-scale deformation behavior of [111], [210] and [001] 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.
