Impact of Feedstock Recycling on the Corrosion Resistance of Inconel 625 Processed by L-DED [PDF]

Materials Research
The corrosion resistance of Inconel 625 processed by L-DED additive manufacturing using virgin and reused powders was investigated to optimize the cost-effectiveness of the process. Samples were manufactured under a controlled argon atmosphere. Feedstock

High intensity x-ray diffraction in transmission mode employing an analog of Poisson's spot [PDF]

, 2010
Poisson’s spot is a diffraction phenomenon producing an intensity maximum at the center of the geometric shadow of circular opaque objects. In an analog of the Poisson spot experiment, we show that a tubular cone of x-rays incident upon a crystalline ...

Adaptive Powder Behavior Model for Dispersion and Recovery in Metal Additive Manufacturing

Powders
Metal additive manufacturing relies on fine powders whose properties influence flow, spreading, and airborne release during processing, yet published data on powder characteristics, reuse effects, and emissions remain fragmented and difficult to compare.

Applicability of reused industrial dry sanding powder for adsorption of arsenic

Water Science and Technology, 2008
This study examined the potential reuse of powdered wastes (PW) generated during the sanding and sawing process in a local chemical company in Korea with the viewpoint of the recycling these wastes and minimizing the level of contamination. As the aluminium hydroxide inside the PW could be thermally converted to various types of aluminium oxides ...
