Reason for Study: Arrangement of atoms is different in various directions & along various planes or surfaces Certain properties will also vary Directional anisotropy Deformation follows particular planes and directions Number and type affect the strength and ductility of materials

Coordinates & Lattice Point Locations Coordinate System By convention, back bottom corner of a cube is selected as the origin Cartesian axes are placed along the edges of the cube The unit of length in a direction is the lattice parameter in that direction Lattice Points Any point in the lattice may now be specified by (x,y,z) coordinates

Miller Indices of Direction: To specify a given direction in the lattice: Determine the coordinate location for two different points lying along the line (start and finish) Subtract the coordinates of the “start” point from the coordinates of the “finish” point to determine
