Assume you have a cube shaped CsCl crystal terminated by six {100} planes. (i) If [001] (110) is the only active slip system, and deformation occurs only by edge dislocations, on what surface(s) do you expect to observe dislocation etch pits? (ii) under the same conditions as (i), on what surface(s) do you expect to observe slip steps? (iii) If [001] (110) is the only active slip system, and deformation occurs only by screw dislocations, on what surface(s) do you expect to observe dislocation etch pits? (iv) under the same conditions as (iii), on what surface(s) do you expect to observe slip steps?
