Summary

Dynamic recrystallization is an important process during deformation of many rock forming minerals, occurring under a wide range of metamorphic conditions. It can strongly influence mechanical properties and the development of microstructure. In this paper, we review existing work on dynamic recrystallization of minerals and mineral analogs. We examine the main driving forces and the processes operating on the grain scale as well as on the scale of grain boundaries, especially considering the case of a fluid filled grain boundary.

It is argued that impurity-hindered grain boundary migration can be significant in dynamic recrystallization of minerals, and a more general classification than the “rotation” and “migration” recrystallization regimes of Poirier and Guillopé (1979) is proposed. We suggest that fabrics which develop during dynamic recrystallization are essentially deformation fabrics, although recrystallization processes can accelerate or modify the fabric.

We review the effects of dynamic recrystallization on flow stress, and conclude the paper with a discussion of whether or not dynamic recrystallization can be called a deformation mechanism.
