In the area fraction and particle size of the same circumstances, when the second-phase particle size fraction of small (less than 5%), the rod-like particles on grain growth pinning the role and the role of spherical particles there is no significant difference; When the second phase particle size fraction large (more than 5%), the rod-like particles pinning the grain boundary effect is better than pinning effect of spherical particles.

under the circumstances that when the area fraction and particle size are the same , if the area fraction of the second-phase particles is small(less than five percent),the function between discal particle and pinning effect of grain growth has unconspicuous differences with the function between  spherical particle and pinning effect of grain growth, else the impression demonstrated by the latter function is the better one

Under the condition of the same area fraction and particle size, there is no difference between discal particles and spherical particles in the pinning effect on grain growth when the second-phase particles is small(less than 5%) ;on the contrary,discal particles play better when the second-phase particles is large(larger than 5%)
