Effects of particle size on inhibited grain growth

Inert, second-phase particles are often dispersed in metallic and ceramic materials to control grain morphology and size. A Monte Carlo computer simulation is used to examine pinned grain growth for a range of particle sizes. The results are in agreement with earlier two- and three-dimensional simul...

Description
Summary:Inert, second-phase particles are often dispersed in metallic and ceramic materials to control grain morphology and size. A Monte Carlo computer simulation is used to examine pinned grain growth for a range of particle sizes. The results are in agreement with earlier two- and three-dimensional simulations. Inhibited grain growth is characterized by two kinetic regimes: a normal growth regime with Dg proportional to t exp n (where Dg is the average pinned grain diameter) followed by a pinned regime with Dg constant.
