Reduction of Silicon from a Ceramic Mold during Directional Solidification of Single-Crystal Nickel Superalloys

详细

Silicon is one of the most harmful impurities in nickel superalloys used for casting aviation turbines: it decreases the high-temperature strength and the ductility. The reduction of silicon from a ceramic mold is experimentally studied during the directional solidification of a single-crystal nickel superalloy.
