- Abstract
We present a model of deformation twinning based on the idea that twin generation is a stress-driven process. Using simple, yet sensible, assumptions regarding the grain size distribution, an equation for the variation of the twin volume fraction with the flow stress is obtained. The model is validated for the case of Mg alloy ZK60 through measurements of the evolving volume fraction of twins by means of direct video observation of the specimen surface and by monitoring the acoustic emission signals.
