The measured plastic deformation of Mg‐PSZ under stress contains contributions from both transformation and microcracking. A method is described to separate the contributions from transformation and microcracking for samples deformed in uniaxial tension. Such a separation enables the ratio of the longitudinal to transverse strains arising from the transformation to be estimated. The results are compared to the predictions of the shear–dilatation model of Chen and Reyes‐Morel. Serious discrepancies are found between the experimental results and the predictions of the model and the possible reason for this is discussed.
