E45: Quiz 11/29/06 NAME:_______________________________________________________________ 1. Specify the Miller indices, {hkl}, of the crystallographic plane on which plastic flow occurs in a metal with the BCC crystal structure. Specify the crystallographic direction, <hkl>, in which plastic flow occurs in the bcc metal. {110}, <111> 2. Which of the following characteristics describes the Buerger’s vector, b , of an edge dislocation? (i) b is in the plane on which the edge dislocation glides (i.e., the closest packed
