In the case of badly deformed fcc and bcc crystals, what is the maximum number of different twin traces that one should expect to find?
What will be an ideal response?
Solution:
In the bcc metals, the maximum number of twin traces could be as high as twelve because there are 12 twinning planes. On the other hand, in the fcc crystals, the maximum number of twin traces is four since there are only four planes, the octahedral planes, on which the twins can form.
