Abstract

This paper summarizes several recent advances in the micro-macro combined experimental study on the mechanical behavior of single crystal shape memory alloys (SMAs) by using the Moire interferometry. The first is the realization of the in-situ full-field deformation measurement on the β1↔γ′1 and β1↔β′1 martensitic transformation and γ′1→γ′1 reorientation processes under uniaxial tensile stress in single crystal CuAlNi SMA. The second is the discovery of distortion of the p-m interface in the case of superelasticity. The third is the observation of the transformation zone development in stress gradient fields of 4-point-bending and notched beams specimen. Implications of these discoveries are discussed briefly.
