Modern theories of the micromechanics of martensitic phase transformations have evolved for nearly 80 years. Experiments to verify these theories at the micro-scale, however, are a relatively new success, as ex-situ observations of these mechanisms are difficult. New non-destructive in-situ High-Energy Diffraction Microscopy (HEDM) 3D X-ray diffraction techniques are being developed to address this gap. Nickel-titanium and iron-palladium shape memory alloys have been used as model materials in the first experiments. In this presentation, we will review the new micromechanical insights and capabilities arising from these experiments and their ability to shed new insights on mechanisms of hysteresis and the mechanics of transformation-plasticity coupling.
