## Abstract The asymmetry associated with martensitic transformations observed in tension/compression experiments of shape‐memory‐alloys (SMAs) is investigated on the basis of a recently suggested micromechanical model. The approach is based on crystallographic theory and utilizes a framework of en

AbstractÐThe purpose of this work is to thoroughly understand tension±compression asymmetry in precipitated NiTi using unique experimental results and micro-mechanical modeling. For the ®rst time, tensile and compressive stress±strain behaviors were established on aged single crystals ([100], [110],
## Abstract In‐situ diffraction investigations of superelastic NiTi shape memory alloys with neutron and synchrotron x‐ray radiation were used to examine the evolution of the phase state of the material as a function of stress and strain, respectively. The results suggest that the transition from a
