In the solid metal the atoms are aligned in even lines, rows and layers, forming three-dimensional crystalline structures. By definition, the metals have the crystalline structure. It is obvious that any reasoning about «crystallization» as the cause of the destruction of metal has no basis for any reason. When solidified, the metal always acquires the crystalline structure. The formation of a fracture surface, which is mistakenly termed «crystal-like» because of its appearance, is typical for cases of fatigue or the brittle fracture.
The smallest number of atoms that form the structure that gives a complete Continue reading →
