IT-HS Deformation Mechanism Activity

Subgrain rotation and glide induced vorticity are the main rotational mechanisms during the first transient stage.

The combination of subgrain rotation, gbm and glide induced vorticity accommodate deformation during the second transient stage. The appearance of some small cracks indicates that fracturingadditionally contributes to bulk deformation.

The steady state mechanism assemblage comprises subgrain rotation, gbm and glide induced vorticity.
