Question Regarding Imperfections in Atomic Arrangement

[RoyalFlush100]

"What are the imperfections in the atomic arrangements that have a significant effect on the material behavior? Give an example of each."

Can someone please explain to me what these imperfections are and why they have a significant effect?

This question is from section 4.7, number 49 of this book: http://home.ufam.edu.br/berti/nanomateriais/0495296023MaterialsEnginee.pdf

See Chapter 4 of that same book.
