Continuous sub-grain rotation type dynamic recrystallization

From Wikipedia, the free encyclopedia

In Metallurgy, Materials Science and Structural geology continuous sub-grain rotation type dynamic recrystallization is recognized as an important mechanism for dynamic recrystallisation. It involves the rotation of intially low-angle sub-grain boundaries until the mismatch between the crystal lattices across the boundary is sufficient for them to be regarded as grain boundaries. Ths mechanism has been recognized in many minerals, including; quartz, calcite, olivine, pyroxenes, micas, feldspars, halite and garnets, and in metals; various magnesium, aluminium and nickel alloys.
