Change in structure of oriented growth of Fe-C eutectic alloys with induction stirring is studied. It is found that eutectic structure coarsens obviously with rotated stirring and graphite lamellar spacing increases with increasing speed gradient of solid/liquid (s/l) interface along the radial direction. It is also found that supercooling at the eutectic front is depressed with increasing growth rate and rotation rate. Assuming a lamellar stationary flow parallel to the growth interface within the liquid boundary layer where the solidification takes place, a simple medel is proposed and compared with the experimental results. A good agreement between the experiment and the theoretical model is
