1. A fcc metal has the slip system of (111)[011]. (a) Give the Burgers vector for a perfect dislocation that slips in the slip system. Illustrate the Burger's vector with a Thompson's tetrahedron. (b) If the dislocation is a pure edge dislocation, give the direction for the dislocation line. What if the dislocation is a pure screw dislocation? (c) Give a slip system that the dislocation can cross-slip into. 1. A fcc metal has the slip system of (111)[011]. (a) Give the Burgers vector for a perfect dislocation that slips in the slip system.
