On the volume fraction dependence of particle limited grain growth

On the volume fraction dependence of particle limited grain growth

An analytical model is presented to account for the different variation of the limiting grain radius with volume fraction of particles found in the computer simulations of Srolovitz, et al. (Acta Metall. , 1984, 32, 1429,) as compared to the classic Zenar predictions. The effect of particles, seen i...

Zusammenfassung:An analytical model is presented to account for the different variation of the limiting grain radius with volume fraction of particles found in the computer simulations of Srolovitz, et al. (Acta Metall. , 1984, 32, 1429,) as compared to the classic Zenar predictions. The effect of particles, seen in both the simulations and the predictions, is to cause grain growth to cease at some limiting grain size. 15 ref.--D.O.N.
