Assume a simple cubic crystal structure with x = [100], y = [010], and z = [001]. Sketch the unit cell for this structure complete with identified xyz directions. In the unit cell, sketch the following two cases, identify the dislocation types (i.e., edge or screw), and determine whether the dislocation interactions affect the mobility of the reacting dislocations.
