"WebThe concept of incoming slip in the right example is thus absurd. A resistance factor of the grain boundary can be described by the following equation: (12) ¶ GBresfac = 1 − m ′. This factor is equal to 0, when grain boundary is transparent to dislocations. This implies m ′ parameter equal to 1 (slips perfectly aligned). " - Trigeminal grain boundary
