Abstract Scope |
In this study, the (Zr, Hf)68.46Cu12.99Ni9.79Al3.66Nb4.59Y0.5 alloy was prepared using vacuum induction melting with the BaZrO3 crucible. The microstructure and oxygen content of the alloy were analyzed, and the interaction was investigated using optical microscope, scanning electron microscope and X-ray diffraction. The results showed no obvious melt erosion layer was found at the bottom of BaZrO3 crucible, and a large number of Y2O3 particles were found attached to the bottom. With the increase of smelting times, the oxygen content in the alloy showed a decreasing trend, and the Y element content in the alloy was significantly lower than the proportion content. It indicated that O generated by the decomposition of the crucible after contact with the melt combines with the free Y in the melt to generate Y2O3 particles deposited at the bottom of the crucible, which hinders the further contact between the melt and the crucible. |
