摘要：
In the present study, solidification and segregation of Al-Li-Cu-Zr alloys have been investigated. Results show that shape of ingots and amount of lithium can change solidification essence. Increasing solidification rate, not only eliminates grain-refining effect of zirconium but also causes coarse segregation of copper in grain boundaries (negative segregation). Increasing amount of lithium in Al-Cu-Li-Zr alloys can change the solubility of other alloying elements (Cu, Zr) and increase solidification range and microsegregation of copper in structure.
