Materials Science

New strain-free grains nucleate and consume a deformed metal's microstructure

In physical metallurgy, recrystallization is the process by which new, strain-free grains nucleate and grow within a plastically deformed metal on heating, replacing the dislocation-rich deformed structure and lowering the stored energy. John Burke and David Turnbull's review Recrystallization and grain growth in Progress in Metal Physics set out the classical kinetics. The referent is the solid-state replacement of deformed grains by new ones, driven by stored deformation energy, the same essential process geologists read in flowing rock.[1]

Unit
One recrystallized grain, replacing deformed material
Recovery means
Anneal a cold-worked metal and watch new equiaxed grains replace the deformed structure
Measured by
Tracked by hardness drop, grain-structure microscopy, and recrystallized-fraction kinetics (JMAK)

Geology

Mineral grains in a deforming rock reorganize into new grains as it flows

In structural geology, dynamic recrystallization is the reorganization of mineral grains during deformation, as strained grains are replaced by new ones through subgrain rotation or grain-boundary migration while the rock flows at depth. Janos Urai, Win Means, and Gordon Lister reviewed the mechanisms in Dynamic recrystallization of minerals in the Geophysical Monograph Series. It is the same stored-energy-driven grain renewal metallurgists study in metals, here recorded in naturally deformed rocks rather than annealed alloys.[2]

Unit
One recrystallized mineral grain in a deformed rock
Recovery means
Identify new, strain-free mineral grains replacing old ones in a mylonite or sheared rock
Measured by
Recrystallized grain size used as a paleopiezometer via microstructural analysis
