Abstract: A method of making a composite core (220) includes forming first (222) and second (224) cores of refractory metal and ceramic material. Each of the first (222) and second (224) cores is formed with two layers of a material. The layers are bonded together to form a laminate master pattern, and a flexible mold is formed around the pattern. The pattern is removed from the flexible mold, and slurry material, either pulverulent refractory metal material or ceramic material, is poured into the flexible mold. The slurry material is sintered to form each core. The first core (222) is used as an insert while making the second core (224) to create a final composite core (220).

Abstract: A method for casting an article comprises a first region and a second region. The method comprises casting an alloy in a shell, the shell having a casting core protruding from a first metal piece; and deshelling and decoring to remove the shell and core and leave the first region formed by the first piece and the second region formed by the casted alloy.

Abstract: The invention relates to a binder system for producing a slurry for a casting core green part. The invention further relates to a component that has been produced by means of such a slurry. The invention is in particular usable for more cost-effective production of complex metal blades in gas and drive turbines of all kinds. According to the invention, a novel binder system is provided for the first time, which combines short gel times at room temperature without solvent, while retaining the high glass transition of 55 to 60°C, with abbreviated hardening periods.
