摘要：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 l
