英文摘要	Hot tearing susceptibility (HTS) refers to the casting defect that existed owing to the appreciable shrinkage at the final stage of solidification. Present research studied the effect of Y on the HTS of 3Y2O3/Al5Cu composite. After 0.3%, 1% and 2% Y (in wt.%) added, the HTS value of 3Y2O3/Al5Cu composite decreased by 2.1%, 39.5% and 61.9%, respectively. Mechanism analysis indicated that the refined grain size and reduced solidification temperature range contributed to the HTS improvement. The grain size of 3Y2O3/Al5Cu was 36.7 μm, while the grain size refined to 32.99 μm, 24.35 μm and 20.9 μm for the 0.3Y-3Y2O3/Al5Cu, 1Y-3Y2O3/Al5Cu and 2Y-3Y2O3/Al5Cu. The result indicated that the increase of grain growth restriction factor, which was caused by the Y element, improved the grain refinement efficiency. Furthermore, adding Y resulted in the novel Al8Cu4Y phase formation and solidification temperature range reduction. In addition, the Al8Cu4Y and Al2Cu phases promoted grain boundary bridges formation and prevented the cracks initiation and growth during solidification process. © 2020 Elsevier B.V.
