Precipitation hardened stainless steels have been recognized for research due to their increased corrosion resistance and tensile strength capability. The current study is focused on AM 17% Chromium � 4% Nickel precipitation hardened (17-4 PH) stainless steel powder. Six (6) identical geometric builds were constructed at the same location using Powder Bed Fusion (PBF) - Direct Metal Laser Sintering (DMLS). After undergoing post-processing treatments, samples were harvested from each build plate for comparative microhardness, and microsample mechanical tensile testing analysis. As a part of a repeatability study, this work aims to determine the impact of manufacturing and post-processing techniques on material properties fabricated by PBF - DMLS.application:pdfThis item may be protected under Title 17 of the U.S. Copyright Law.
