摘要

A new selection criterion to explain the activation of the twinning variant is proposed based on the calculation of the deformation energy to create a primary twin. The calculation takes into account the effect of the grain size using a Hall-Petch type relation. This criterion allows to obtain a very good prediction for the variant selection. The calculations are compared with the experimental results obtained on T40 deformed by Channel Die compression.
