The powder characterization methods in AM are can be separated into three categories: particle morphology, particle chemistry, and particle microstructure which are all important when selecting and/or optimizing a powder for any given process.
This research has investigated few of these characteristics and further studies will include investigating the presence of porous structures if any in the powders as well as the oxygen gains during processing.
