Recrystallization is defined as the process in which grains of a crystal structure come in a new structure or new crystal shape. A precise definition of recrystallization is difficult to state as the process is strongly related to several other processes, most notably recovery and grain growth.

WebSep 30, 2024 · What Does Recrystallization Mean? Recrystallization is the process in which deformed grains of the crystal structure are replaced by a new set of stress-free grains that nucleate and grow until all the original grains have been consumed. The process is accomplished by heating the material to temperatures above that of crystallization.

WebThe crystals which form in the process of solidification of a metal may have many different structures (dendritic, lamellar, needle-type or acicular etc.) depending on the rate of cooling, and the type and amount of mixtures or impurities in the melt. WebThe presence of impurities decreases the rate of growth, i.e., recrystallization rate. When all the cold worked metal grains have been replaced by grains of strain free crystal structure, the growth stops and recrystallization is said to be complete. Laws of Recrystallization: 1. A minimum deformation is necessary for recrystallization. 2.
