Abstract The effect of Al atoms in solid solution on the critical resolved shear stress for twin nucleation and growth was analyzed by means of the combination of diffusion couples with compression tests in micropillars oriented for twinning. The critical resolved shear stress for twin nucleation was higher than that for twin growth and both increased by the same amount with the Al content. Nevertheless, the increase was small (≈ 10 MPa) for 4 at%Al but large (up to 60–70 MPa) for 9 at%Al…

TLDR
A ‘stimulated slip’ model is developed to explain the strong size dependence of deformation twinning in crystals, and the sample size in transition is relatively large and easily accessible in experiments, making the understanding of size dependence relevant for applications.
