diffusion across dislocation and grain boundary will depend on the deriving force. Diffusion across dislocation and grain boundary possible but the rate is slower

Correct answer is option C. @Gaurav Kumar described it best. Thank you. Some peripheral lines related to this topic: Atomic migration is related to driving force available for diffusion across dislocation and grain boundary. So it will always occur, the only thing which varies is the rate of migratRead more
