| Abstract Scope |
NASA HR-1 was developed to expand the field of high-strength, hydrogen resistant alloys available to the aerospace community. Quadrus Advanced Manufacturing (QAM) developed three different laser powder bed fusion (L-PBF) additive manufacturing (AM) build parameters for this alloy. QAM explored the effect parameters developed at 135W, 150W, and 180W on both the microstructural and mechanical behavior of the material. QAM prepared metallographic specimens and performed uniaxial tension testing with specimens built in the X-Y build plane and the Z-build direction to decide which of the three parameter sets should be used for the preliminary Qualified Metallurgical Process (QMP). All three parameters displayed equiaxed grain structures and impressive mechanical properties, but one resulted in a more refined microstructure than the others. QAM then created 18 metallographic specimens and 100 tensile specimens to develop a preliminary QMP for HR-1. Resulting in a sufficiently baselined material property suite. |
