| Abstract: | Heal transfer,mass transfer and structure of Al alloy ingots were investigated experimentally under the action of a rotary magnetic field,i.e., the rotary electromagnetic stirring. The reason why inclined columnar crystals are formed under such a rotary movement is discussed so as to define critical concentration of inclined columnar crystalline solute and some other principles concerned of Al-Cu alloy. The reason why characteristic segregation is caused by electromagnetic stirring is also discussed. |

| Keywords: | Al alloy ingot rotary electromagnetic stirring inclined columnar crystal characteristic segregation |
