1. Write down all the possible Burgers vectors of perfect dislocations in an FCC metal. 2. For an a/2[1 dislocation line moving on a (11-1) plane in an FCC crystal, what are the line directions (in Miller indices) if the dislocation is of (i) pure screw and (ii) pure edge character? For an a/2[1 dislocation line moving on a (11-1) plane in an FCC crystal, what are the line directions (in Miller indices) if the dislocation is of (i) pure screw and (ii) pure edge character?
