  • ANALYSIS OF ADDITIVELY MANUFACTURED 17-4PH

    2019-3-25 · precipitation treatments lead to the desired changes in microstructure. The research within this thesis establishes that there is up to 0.12wt% higher nitrogen content within additively manufactured 17-4PH, compared to traditionally manufactured 17-4PH, as a result of the powder atomization process.
