Recrystalization method
it is deformation below recrystalization temperature.
Because it readily dissolves polar substances. Besides being cheap and "green"
CRCA: Cold rolled close annealed,the sheet is rolled below the recrystalization temaparature of the steel,this type of sheets will have close tolerance,good finish and better mechanical strength HRCA: Hot rolled and close annealed, here the steel is rolled above the recrystalization temparature,this type of sheets have coarse finish, rough surfaces and less mechanical strength compared to CRCA
recrystalization is a method of purification of compounds that are solids at room tempreture the process of recrystalization involves dissolving the compound in hot solvent and then cooling solution cooling process : slow (crystalization) fast (precepitayion)
- centrifugation - filtering - electromagnetic separation - radiometric separation - gravimetric separation - distillation - sieving - freeze drying - crystallization/recrystalization - zone melting - manual separation etc.
there r mny application of recrystallisation..........if u knw write d answer on dis page.....jst chillax.... It is just to increase the purity of crystals from the homogenous solutions of the dissolved crystals.
Recrystallization of unmelted material under high temperature and pressure can result in the formation of metamorphic rocks such as marble from limestone or quartzite from sandstone.

Recrystalization takes deformed metal crystal grains and allows them to reform without the deformations. This usually results in the metal becoming less strong, less hard (softer), and more ductile. This allows the metal to be worked more easily.

The full question is: What may be involved with metamorphism EXCEPT A recrystalization into denser minerals B new minerals forming in the solid state C increased temperature or pressure D hydrothermal activity E melting of existing rock E melting of existing rock is not part of metamorphism
