Theory reveals the nature of crystals defects (of silicon carbide)

A crystallographic defect is an interruption of the regular patterns of arrangement of atoms or molecules in crystalline solids. The positions and orientations of particles, which are repeating at fixed distances determined by the unit cell parameters in crystals, exhibit a periodic crystal structure, but this is usually imperfect. Several types of defects are often characterized: point defe… http://www.gemstones-guide.com/Characteristic-Imperfection.html boys town family home program

WitrynaAbstract. Crystal imperfections affect the stress–strain diagram in a number of ways, often increasing the tensile strength as the density of imperfections increase or their geometry creates partitioning of the crystal structure. Work hardening and strain hardening are also dependent upon imperfections. WitrynaImperfections in Solids Generally, an idealized solid (perfect order exists throughout crystalline material) i.e., real perfect crystal does not exist; all contain large numbers of various defects or imperfections. Many of the important properties of materials are due to the presence of these imperfections.
