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 or control strategy in a coating apparatus for use in a coating process can include controlling differential gas pressures among multiple selected localized zones in a coating chamber with respect to each other. The controlled differential gas pressure of the multiple selected localized zones is used to influence how a coating deposits on at least one component. The localized zones can be selected from a first localized zone around the component, a second localized zone adjacent the source of coating material, a third localized zone that diverges from the second localized zone toward the first localized zone, and a fourth localized zone that circumscribes at least the third localized zone.

Abstract: A method of evaluating and validating additive manufacturing operations includes generating a multidimensional space defined by a plurality of bounds, each of the bounds being defined on a distinct parameter of an additive manufacturing process and each of the bounds being directly related to the occurrence of a downskin roughness flaw, each of the parameters being a dimension in a multi-dimensional coordinate system, determining a coordinate position of at least one additive manufacturing operation within the multi-dimensional coordinate system, and categorizing the operation as free of downskin roughness flaws when the coordinate position is within the multi-dimensional space.

Abstract: A powder processing machine includes a work bed, a powder deposition device operable to deposit powder in the work bed, at least one energy beam device operable to emit an energy beam with a variable beam power and direct the energy beam onto the work bed with a variable beam scan rate to melt and fuse regions of the powder, and a controller operable to dynamically control at least one of the beam power or the beam scan rate to change how the powder melts and fuses. The controller is configured to determine whether an instant set of process parameters falls within a defect condition or a non-defect condition and adjust at least one of the beam power or the beam scan rate responsive to the defect condition such that the instant set of process parameters falls within the non-defect condition.

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.
