Abstract: A method of making an airfoil includes making a refractory metal core that defines an interior of the airfoil by a tomo-lithographic process, making a mold that defines an exterior of the airfoil, inserting the refractory metal core into the mold, and pouring an airfoil material between the refractory metal core and the mold to cast the airfoil.

Abstract: A process for directional solidification of a cast part comprises energizing a primary inductive coil coupled to a chamber having a mold containing a material; generating an electromagnetic field with the primary inductive coil within the chamber, wherein said electromagnetic field is partially attenuated by a susceptor coupled to said chamber between said primary inductive coil and said mold; determining a magnetic flux profile of the electromagnetic field after it passes through the susceptor; sensing a component of the magnetic flux in the interior of the susceptor proximate the mold; positioning a mobile secondary compensation coil within the chamber; generating a control field from a secondary compensation coil, wherein said control field controls said magnetic flux; and casting the material within the mold.

Abstract: An induction furnace assembly comprising a chamber having a mold; a primary inductive coil coupled to the chamber; a susceptor surrounding the chamber between the primary inductive coil and the mold; and a shield material contained in a reservoir coupled to or proximate the mold between the susceptor and the mold; the shield material configured to attenuate a portion of an electromagnetic flux generated by the primary induction coil that is not attenuated by the susceptor.

Abstract: A system and methods are provided for removing core elements of cast components. In one embodiment, a method includes controlling a first high temperature autoclave cycle for a cast component in a vessel with a first solution concentration to remove at least a first portion of core elements, wherein the first solution concentration, temperature and pressure in the vessel are controlled to expose one or more casting pins in the cast component. The method may also include controlling a second high temperature autoclave cycle for the cast component in the vessel with second solution concentration, wherein the second solution concentration, temperature and pressure in the vessel during the second high temperature autoclave cycle are controlled to loosen one or more of the casting pins from the cast component, and controlling one or more low temperature autoclave cycles to remove core and casting pins from the cast component.
