Question - How Does And Why The Recrystallization Temperature Of The Metals Affects On Alloying?
Answer -
The formation of new equiaxed grains in the heating process, instead of the oriented fibrous structure of the deformed metal is called re crystallizations. The temperature required for the beginning of the re crystallizations is characteristic of each metal but depends on number of factors and firstly up on the degree of deformation. The higher the degree of deformation, the lower the re crystallizations temperature will be.
In the process of the re crystallization of such metals as iron, copper, and aluminum, the new crystals sometimes grow in an oriented arrangement and the so called re crystallization texture is obtained.
The effect of foreign atoms in solid solution on the rate of re crystallization is almost apparent at very concentrations. The change in the re crystallization temperature caused by the presence of foreign atoms depends markedly up on the nature of the solute atoms.
