Reorganization of elements of the original minerals in a rock resulting from changes in temperature and pressure and from the activity of pore fluids.
A stage of the restoration process that replaces the work-hardened grains with a new set of strain-free grains.
the formation of destructive intracellular ice crystals through combinations of smaller ice nucleations during the process of thawing
the formation of a new set of strain-free grains within a previously cold-worked material; normally an annealing heat treatment is necessary.
(1) Formation of a new, strain free grain structure from that existing in cold worked metal, usually accomplished by heating. (2) The change from one crystal structure to another, as occurs on heating or cooling through a critical temperature.
This describes the condition of a metal structure that has changed from one crystal structure to another, usually from a work-strained structure to a strain-free grain structure. The condition is attained through specific heat treatments.
The change in grain structure which occurs when the metal is annealed, during which the deformed grains, strain hardened by working, become new unstrained grains.
A process whereby the distorted grain structure of cold-worked metals is replaced by a new, strain-free grain structure during annealing above a specific minimum temperature.
The process in which ions or atoms in minerals rearrange to form new minerals.
The formation of new mineral grains as a result of changes in temperature, pressure, or other factors.
Recrystallization (see also crystallization) is an essentially physical process that has meanings in chemistry, metallurgy and geology.
Recrystallization is a process by which deformed grains are replaced by a new set of undeformed grains that nucleate and grow until the original grains have been entirely consumed. Recrystallization is usually accompanied by a reduction in the strength and hardness of a material and a simultaneous increase in the ductility. Thus, the process may be introduced as a deliberate step in metals processing or may be an undesirable by product of another processing step.
