Abstract Scope |
C103 is a readily-fabricable, niobium alloy with improved elevated temperature properties compared to commercially pure niobium. This moderate strength at elevated temperatures niobium alloy is desirable for reaction control systems (RCS) that could be produced via additive manufacturing. However, elevated temperature mechanical properties of additively manufactured C103 do not currently exist in open literature. Therefore, uniaxial tension samples were fabricated by laser powder bed fusion (L-PBF) from commercially available C103 spherical powder feedstock. The additively manufactured material was mechanically tested at elevated temperatures in a controlled environment in the as-built and post hot isostatic pressing (HIP) conditions. For comparison, traditionally manufactured wrought feedstock was also tested in the as-worked and recrystallized conditions. |
