Abstract
The effect of antimony on the grain growth of zone-refined tin is markedly different from the effects of other solutes. It is suggested that, since antimony has a distribution coefficient greater than unity in tin, the antimony will not segregate positively to the grain boundaries and will thus be pushed ahead of an advancing boundary during grain growth. The effect of simultaneous diffusion of antimony in the matrix ahead of the boundary during the grain growth is also discussed.
