Abstract: A method for determining a melt strategy for an additive manufacturing system comprises: receiving geometry data corresponding to a surface of a powder layer; populating the geometry data with melting points; assigning at least one treatment action to each melting point; assigning a melt parameter and a prerequisite thermal characteristic to each treatment action; generating a preliminary list; creating a revised order comprising a plurality of sequential unpopulated items; and populating the revised order by: identifying an earliest unpopulated item, determining if any treatment action comprises prerequisite thermal characteristics satisfied for a time of the earliest unpopulated item, assigning an assignment to the earliest unpopulated item; removing the treatment action comprising prerequisite thermal characteristics which are satisfied for the sequential time of the earliest unpopulated item from the preliminary list, classifying the earliest unpopulated item as a populated item, and returning to identifying the earliest unpopulated item.

Abstract: An additively manufactured article comprises a superalloy composition and a microstructure. The microstructure comprises a gamma-prime phase greater than or equal to 35% by volume of the microstructure. The microstructure comprises grains having an average aspect ratio of greater than or equal to 5.

Abstract: A device for viewing and/or illuminating a target surface in an evacuated chamber having condensable vapor therein, the device comprising: a first section with a through hole having a first end with a first opening and a second end with a second opening; and a second section having a chamber comprising a first portion with a first opening, a second portion with a second opening and a gas inlet, where the second opening is covered with a first window, said first section is attached with the first end to the first portion of the chamber allowing free passage between the chamber and the first section, said gas inlet is connectable to a gas reservoir for feeding a gas into the chamber for prohibiting the first window in the chamber for being contaminated of the condensable vapor.
