Crystallographic shear planes

WebThe configuration of the basis plane (0001) is shown in Fig. 1. The atoms of the "upper" plane are marked by the circles of bigger sizes, the atoms of the "low" plane - by the circles of less sizes. The direction of. advantageous shear, forming the planar defect in the basis planes, are < 12 3 0 > , in the prismatic planes - < 2203 > and < 1210 > . WebNote: The hkl indices define a vector that starts at the origin and it perpendicular to the plane. Recall from your multi-variable or vector calculus class that the equation of a plane can be written as a!x + b!y + c!z = d, where the vector [abc] is perpendicular to the plane. In our case, a crystallographic plane can be written as h!a +k! b ...
