·­Ò룺The pinning effect of second phase particles on grain growth comes from two aspects, namely, the size and the number of second phase particles. In general, second phase particles with smaller size have greater pinning effect on grain growth on the conditions of same volume fraction of second phase particles.

Two aspects of the second phase particles could influence the pinning effect on grain growth. One is the size, and the other is the number.  The second phase particles with smaller size have greater pinning effect on grain growth when their volume fraction was kept the same.
