Crystallographic defect - Wikipedia, the free encyclopedia 跳到 Point defects - Point defects are defects that occur only at or around a single lattice point. They are not extended in space in any dimension.
Vacancy defect - Wikipedia, the free encyclopedia In crystallography, a vacancy is a type of point defect in a crystal. Crystals inherently possess imperfections, sometimes referred to as crystalline defects. A defect ...
Defects in Crystals - Materials Science & Engineering 4.2 POINT DEFECTS. A point defect disturbs the crystal pattern at an isolated site. It is useful to distin- guish intrinsic defects, which can appear in a pure material ...
Crystallographic defect The regular patterns are interrupted by crystallographic defects. ... Strict limits for how small a point defect is, are generally not defined explicitly, but typically ...
Crystal Defects Crystal Defects A perfect crystal, with every atom of the same type in the correct position, does not exist. All crystals have some defects. Defects contribute to the mechanical properties of metals. In fact, using the term ...
crystal defect (crystallography) -- Encyclopedia Britannica crystal defect, imperfection in the regular geometrical arrangement of the atoms in a crystalline solid. ... Located at single points, along lines, or on whole surfaces in the solid, these defects influence its mechanical, electrical, and optical behaviou
