Questions

Quick questions

You should be able to answer these questions without too much difficulty after studying this TLP. If not, then you should go through it again!

  1. What is crystallographic texture?

    a The distribution of orientations of crystallites within a polycrystalline sample.
    b The orientation of a polycrystalline sample.
    c The distribution of orientations of crystallites within a single crystal.
    d The orientation of a surface of a sample.

  2. Which of these are limitations of pole figures? (Select all that apply)

    a Specific hkl planes cannot be plotted
    b Poles in the final plot for a polycrystalline material are not identified with particular crystals
    c Information about the crystallite location in a sample is absent
    d The orientation of a crystal must be described relative to another

Deeper questions

The following questions require some thought and reaching the answer may require you to think beyond the contents of this TLP.

  1. A sample of rolled a-brass (ccp) has a very strong (110) [12] texture. Using a Wulff net, sketch stereograms showing the distribution of 111 and 200 poles with respect to the normal to the sheet and the rolling direction.
