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!
What is crystallographic texture?
A. The distribution of orientations of crystallites within a polycrystalline sample. A random texture describes a sample in which the crystallographic axes of the crystallites are oriented randomly, whereas a non-random distribution means that the material has crystallographic texture.
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|
B and C
The following questions require some thought and reaching the answer may require you to think beyond the contents of this TLP.
A sample of rolled a-brass (ccp) has a very strong (110)  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.
When plotting the stereogram, begin by plotting the rolling direction (RD)  on the primitive of the stereogram and the normal direction (ND)  at the centre.
Remember that rolled sheets always have mmm symmetry
