Abstract
In this study, Alloy 625-based nanocomposites reinforced with varying amounts of tungsten carbide (WC) were fabricated using arc casting. Both the unmodified Alloy 625 and the Alloy 625–WC nanocomposites exhibited a characteristic dendritic microstructure. Segregation of alloying elements into interdendritic regions during solidification promoted the formation of carbides and intermetallic Laves phase precipitates. Partial dissolution of WC nanoparticles during solidification facilitated the formation of additional MC and M₆C carbides, while simultaneously reducing the amount of Laves phase. Air oxidation tests at 800 °C revealed that WC-reinforced nanocomposites possessed superior oxidation resistance due to the formation of a protective Cr₂O₃ layer. Furthermore, the incorporation of WC nanoparticles enhanced the hardness of Alloy 625.
