WitrynaRecrystallization is a common method used to purify a sample. As the name implies a solid sample with suspect purity is dissolved into an appropriate solvent. The dissolution process is achieved heating or changing the pH. WitrynaThe orientation distribution of the recrystallized grains forming at the early stages of the recrystallization dominated the final recrystallization textures, pointing to the importance of oriented nucleation in the formation of recrystallization textures of interstitial-free steels.

WitrynaRecrystallization is the most important method of purifying nonvolatile organic solids. Recrystallization involves dissolving the material to be purified (the solute ) in an appropriate hot solvent. As the solvent cools, the solution becomes saturated with the … WitrynaThe technological importance of grain growth stems from the dependence of properties, and in particular the mechanical behaviour, on grain size. In materials for structural application at lower temperatures, a small grain size is normally required to optimise the strength and toughness.
