On the volume fraction dependence of particle limited grain growth
Journal Article
·
· Scr. Metall.; (United States)
The purpose of this paper is to offer an analytical model that accounts for the different variation of the limiting grain radius with volume fraction of particles found in previous computer simulations as compared to the classic Zener predictions. The effect of particles, seen both in the simulations and in the predictions, is to cause grain growth to cease at some limiting grain size. The source of the discrepancy arises from Zener's assumption of random particle/grain boundary intersections. The computer simulation, on the other hand, shows a high correlation between boundaries and particles.
