| Abstract: | Data are presented for the grain refining of AI-Si and Pb-Sb alloy systems. These show a minimum grain size near the maximum solubility limit. An explanation in terms of the solidification interval is presented. In general, the optimum grain refining is predicted to occur at the solubility limit since t is at this concentration that the solidification times are longest. |
