Relationship between grain Boundary Curvature and Grain Size
Abstract
The relationship between the average mean grain boundary curvature,H, and the mean linear grain intercept, λ, has been experimentally determined for aluminum. The ratioH/λ- 1 = 0.31 was found to remain constant throughout grain growth. This value yields a driving pressure for grain growth approximately three times smaller than that derived by conventional modeling and yields realistic results in models of particle- or pore-inhibited grain growth.
