It was revealed that a "lamellar eutectic → anomalous eutectic" transition occurred with decreasing drop diameter. The results of TMK model indicated that the maximum growth velocity, the minimum interlamellar spacing, and the largest undercooling of Ag-28.1Cu alloy for regular lamellar eutectic growth were 0.291 m/s, 0.017 μm and 193K respectively. A conspicuous grain refinement effect took place as droplet size decreased. The minimum measured eutectic interlamellar spacing was 0.092 μm, corresponding to a calculated eutectic growth velocity of 9.6 mm/s.
