摘要：The interaction between refractory and inclusions in Ni-based superalloys during melting plays a critical role in alloy performance. To clarify the influence of refractory on inclusion characteristics, K4169 Ni-based superalloys was melted in laboratory tube furnaces using crucibles made of Y2O3-based, MgO-based, and Al2O3-based refractories. The results indicate a clear correlation between inclusion types and refractory composition. Al2O3 inclusions predominated melted with Y2O3-based and Al2O3-based refractory, whereas MgOAl2O3 composite inclusions formed when MgO-based refractory were used. It indicated that alloys melted in Y2O3-based refractory contained the lowest inclusion number density with a uniform distribution. Furthermore, capillary force between refractories and inclusions was predicted based on Kralchevsky-Paunov (K-P) model and it followed the order: MgO-based > Al2O3-based > Y2O3-based. This trend was consistent with the experimentally observed inclusion characteristics, confirming that capillary interaction, together with melt-refractory reactions and transport processes, plays a key role in governing inclusion aggregation and distribution. In summary, Y2O3-based refractory demonstrate relatively weak interactions with the inclusion, which mitigates inclusion aggregation and coarsening.
