Dynamic recrystallisation and the development of microstructure during the high temperature deformation of magnesium
TL;DR: The mechanism of dynamic recrystallisation at temperatures between 425 and 600 K is reported to not involve significant high angle boundary migration, but to be similar to a mechanism reported for several minerals.

Large strain deformation studies using polycrystalline magnesium as a rock analogue. Part I: grain size paleopiezometry in mylonite zones
TL;DR: The results of large strain deformation studies of polycrystalline magnesium are reported in this article, showing that the recrystallised grains in the areas bordering the shear zones undergo a strain dependent coarsening and their sizes re-equilibrate to the relaxed stresses at natural strains of 1.65 Tm for strain rates between 10−4−10−5 s−1.

Effect of dynamic recrystallization on the importance of grain-boundary sliding during creep
TL;DR: In this paper, a comparison has been made between the experimental results and some theoretical models for the importance of GBS during creep, modified to take account of recrystallization, and the best fit to the data is obtained with the modified form of Langdons model.

Large strain deformation studies using polycrystalline magnesium as a rock analogue. Part II: dynamic recrystallisation mechanisms at high temperatures
TL;DR: In this article, the authors investigated the dynamic recrystallisation mechanisms in a magnesium alloy during uniaxial large strain compression at T = 0.7−0.95 Tm (Tm = melting temperature).
