Abstract

The hypothesis is presented that mechanical twinning is the result of a stress-assisted martensitic transformation, rather than being a deformation mechanism acting in response to a shear stress. The geometry of the proposed mechanism is shown to be in agreement with the behavior observed in the bcc lattice, and in fair agreement with that reported for the hcp lattice. The hypothesis presented can account for many similarities between mechanical twinning and martensitic transformation, as well as for a number of anomalous observations on various aspects of twinning.
