Abstract: A directional solidification apparatus includes a mold heating chamber, a solidification chamber, and a gas source. The solidification chamber is adjacent the mold heating chamber for solidifying molten metal formed from an air melt allow system as a cast body as the metal is withdrawn from the mold heating chamber. The gas sources is in fluid communication with the mold heating chamber for providing a pressurized atmosphere for directionally solidifying metal as cast body having single crystal or multi-crystal columnar micro structure.

Abstract: A method of investment casting includes casting a liquid nickel- or cobalt-based superalloy in an investment casting mold. The superalloy includes an yttrium alloying element that is subject to reactive loss during the casting. Loss of the yttrium is limited by using a zircon-containing facecoat on a refractory investment wall in the investment casting mold. The facecoat contacts the liquid nickel- or cobalt-based superalloy during the casting. Prior to the casting, a zircon-containing slurry is used to form the facecoat. After solidification of the nickel- or cobalt-based superalloy, the refractory investment wall is removed from the solidified superalloy.

Abstract: A method of forming a hybrid component having an axis of rotation includes forming a first substrate having a first interface surface and a first average grain size, forming a second substrate having a second interface surface and a second average grain size different from the first average grain size, and inertia welding the first and second substrates at a junction of the first and second interface surfaces to form a solid-state joint between the first and second substrates.

Abstract: Methods are provided for manufacturing a component. In one method, first material is cast into a first body. At least a portion of the first body is machined. Second metal material is cast onto at least the machined portion of the first body to form a monolithic second body. A first portion of the second body is formed by the first metal material. A second portion of the second body is formed by the second metal material. The second metal material is different from the first metal material.

Abstract: A high-temperature die casting die includes a first die plate with a first recess and a second die plate with a second recess, the first and second recesses defining a main part cavity and gating. A grain selector is in fluid communication with the main cavity, and an in situ zone refining apparatus is adapted to apply a localized thermal gradient to at least one of the first and second die plates. The localized thermal gradient and the at least one die plate are movable relative to each other so as to apply the localized thermal gradient along a first direction extending from the grain selector longitudinally across the main part cavity.
