Abstract: In an embodiment, an apparatus for forming a metal component from alloy powder includes a powder-based layer-by-layer directed energy beam additive manufacturing system, a primary directed high energy beam, configured to raise a temperature of the alloy powder to or above the melting point of the alloy powder. A secondary directed low energy beam configured to raise the temperature of the alloy powder to or above a sintering point of the alloy powder without reaching the melting point of the alloy powder. The apparatus further includes a sintered region on the surface of an alloy powder layer previously produced by the secondary directed low energy beam and a solid region forming a portion of the metal component that was solidified from a molten pool on the surface of the alloy powder layer adjacent to the first sintered region having been produced by the primary directed high energy beam.

Abstract: A method of additively manufacturing includes determining a track for manufacturing a layer of a component with a powder blend; traversing the track with a conditioning energy beam to cause sintering of powder particles along a denuded region within the powder blend; and traversing the track with a melting energy beam subsequent to the conditioning energy beam to from the layer of the component. An additive manufacturing system includes a build chamber that contains a powder blend; a controller operable to determine a track for manufacturing a layer of a component with the powder blend in the build chamber; a conditioning energy beam directed along the track by the controller to cause sintering of powder particles along a denuded region within the powder blend; and a melting energy beam directed along the track by the controller subsequent to the conditioning energy beam to form the layer of the component.

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; energizing a primary inductive coil within the chamber to heat the mold via radiation from a susceptor, wherein the resultant electromagnetic field partially leaks through the susceptor coupled to the chamber between the primary inductive coil and the mold; determining a magnetic flux profile of the electromagnetic field; sensing a magnetic flux leakage past the susceptor within the chamber; generating a control field from a secondary compensation coil coupled to the chamber, wherein the control field controls the magnetic flux experienced by the cast part; and casting the material within the mold under the controlled degree of flux leakage.

Abstract: A system for the x-ray topography analysis of a sample, comprising in combination, a goniometer having a base, a tube arm rotatably associated with the base, a detector arm rotatably associated with the base, and a sample stage operatively associated with the base. The system also includes an x-ray source operatively coupled with the tube arm and is capable of emitting a non-collimated beam of x-rays. A collimator is operatively associated with the x-ray source and converts the non-collimated beam of x-rays into a collimated beam of x-rays having a quasi-rectangular shape with a divergence less than three degrees in all directions. A detector operatively coupled to the detector arm.
