Hi all please help,

Anybody knows why grain boundaries act as sink for vacancies? in a detailed and microscopic way such as relation to free energy and stuff like that.

I have tried to search everywhere but I am confused about the reason why grain boundaries and dislocations are sink for vacancies.

Would be nice if there're sources explaining about it.

Thank you in advance!!!
