Burger Vectors in HCP metal

  1. Nov 12, 2011 #1
    1. The problem statement, all variables and given/known data

    sketch atomic arrangement, label coordinate axes, determine miller indices of the plane and the burger orientations in the slip plane of an HCP metal.

    2. Relevant equations
    no equations neeeded


    3. The attempt at a solution

    I know the atomic arrangement, a close packed hexagon on top and bottom and a triangle in the middle.

    Coordinate axis are simple, a1, a2, a3, c

    Miller indices of slip plane, (0 0 0 1) this is the close packed plane (it has the highest linear density) and it does not intersect any of the a axes

    I am having trouble with the orientation of the burger vectors. My book gives that there are 3 "slip systems" , the slip plane is (0 0 0 1) and the slip direction is <1 1 -2 0>

    My issue is, how do I find and draw the Burger vector orientations?
