摘要：The effects of ZrO_(2)-based refractory materials on non-metallic inclusions in nickel-based superalloy K4169 were systematically investigated.Analytical methods,including X-ray fluorescence,X-ray diffraction,scanning electron microscopy equipped with energy dispersive spectrometry,and FactSage simulations,revealed that the refractory primarily consisted of ZrO_(2),MgO,MgO·Al_(2)O_(3),and Zr_(1.74)Y_(0.26)O_(3.87) phases.During melting,MgO reacted with[Al]and[O]in the alloy,forming MgO·Al_(2)O_(3) at the interface.This phase adhered to the superalloy,while ZrO_(2) phases remained stable.The inclusions in the alloy transformed from Al_(2)O_(3) to MgO·Al_(2)O_(3),with variations in size and distribution influenced by location and pressure.FactSage kinetic simulations aligned with experimental findings,elucidating the interaction mechanisms between the alloy and refractory.These results provide insights into optimizing refractory materials for improved cleanliness and performance in nickel-based superalloy production.
