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? Assume you have a cube shaped CsCl crystal terminated by six {100} planes.

i When deformation occurs by edge dislocations the dislocations move along the slip planes where they are most favorably oriented In the case of a CSCI crystal with six 100 planes the active slip planes will be 110 because the slip direction is 001 and the slip plane normal is 110 The dislocation motion causes the crystal to deform and leave behind etch pits on the slip planes where the ...
