英文摘要This study explored the influence of strong static magnetic field (SSMF, > 20 T) on growth behavior of faceted Al2Cu intermetallic compounds (IMCs) in Al-40 wt%Cu alloy by using X-ray computed tomography. The growth process of Al2Cu IMCs is influenced by both cooling rates and SSMF. In the absent of SSMF, morphologies of Al2Cu showed four types which were L-shaped, U-shaped, rectangular and stacked clusters at low cooling rate, while high cooling rates led to dendritic shape. In the present of magnetic field, IMCs tended to maintain the rodlike shape despite the increase in cooling rate. With the increase of magnetic flux density at a constant cooling rate, the size of Al2Cu initially increases and then remains constant. Variations in interface growth supercooling at the growth front and magnetic crystalline anisotropy of IMCs are the causes of changes in morphology and size of Al2Cu. The diffusive melt condition created by SSMF slowed down the coarsening process. These findings not only provide a deeper understanding of alloys solidification under the SSMF but also open the avenues for manipulation strategies of innovative IMCs.
