In chemistry, <b>recrystallization is</b> a technique used to purify chemicals. By 
dissolving both ... Heating <b>is</b> not <b>required</b> for this technique but <b>can</b> be used. ... 
This <b>can</b> be spontaneous or <b>can</b> be <b>done</b> by adding a small amount of the pure 
compound&nbsp;... <b>Recrystallization is</b> a process by which deformed grains <b>are</b> replaced by a new 
set of defect-free grains that nucleate and grow until the original grains <b>have</b> 
been entirely consumed. ... During plastic deformation the work <b>performed is</b> the 
integral of the stress and strain in the plastic deformation regime. Although the 
majority&nbsp;... Hot working process metals <b>are</b> plastically deformed above their <b>recrystallization</b> 
temperature. ... Many kinds of working, including rolling, forging, extrusion, and 
drawing, <b>can</b> be <b>done</b> with hot metal. ... The stringers act as &quot;crack-arrestors&quot; 
because the crack will <b>want</b> to propagate through the stringer and not along it. In metallurgy and materials science, annealing <b>is</b> a heat treatment that alters the 
physical and sometimes chemical properties of a material to increase its ductility 
and reduce its hardness, making it more workable. It involves heating a material 
above its <b>recrystallization</b> temperature, ... If annealing <b>is</b> allowed to continue once 
<b>recrystallization</b> has <b>completed</b>, then&nbsp;... Diastereomeric <b>recrystallisation is</b> a method of chiral resolution of enantiomers 
from a racemic mixture. It differs from asymmetric synthesis, which aims to 
produce a single enantiomer from the beginning, in that diastereomeric 
<b>recrystallisation</b> separates two enantiomers that <b>have</b>&nbsp;... In geology, solid-state <b>recrystallization is</b> a metamorphic process that occurs 
under temperature and pressure where atoms of a mineral <b>are</b> reorganized by&nbsp;... In metalworking, rolling <b>is</b> a metal forming process in which metal stock <b>is</b> passed 
through one ... If the temperature of the metal <b>is</b> above its <b>recrystallization</b> 
temperature, then the process <b>is</b> known as hot rolling. ... Most steel mills <b>have</b> 
rolling mill divisions that convert the semi-finished casting products into finished 
products. Recovery <b>is</b> a process by which deformed grains <b>can</b> reduce their stored energy 
by the removal ... Recovery <b>is</b> related to the similar process of <b>recrystallization</b> 
and grain growth, each of them being stages of annealing. ... energy, but <b>is</b> also 
thought to be a <b>necessary</b> prerequisite for the nucleation of <b>recrystallized</b> grains. Dynamic <b>recrystallization</b> (DRX) <b>is</b> a type of <b>recrystallization</b> process, found within 
the fields of ... The final grain size increases with increased stress. To achieve 
very fine-grained structures the stresses <b>have</b> to be high. Some authors <b>have</b> 
used&nbsp;... Quartz <b>is</b> the most abundant single mineral in the earth&#39;s crust (behind the 
feldspar group), and ... Two main mechanisms for altering grain boundaries <b>have</b> 
been defined. The first <b>is</b> the ... temperatures. Furthermore, this <b>is</b> an analysis that 
<b>can</b> be <b>done</b>, if only preliminarily, in the field by observing rocks in hand sample.
