Mechanical Characterization of Additively Manufactured C103

With the growing demand for lightweight, high-performance components in the aerospace and defense sector, additive manufacturing has emerged as a crucial technology for enhancing design flexibility and material efficiency. This study focuses on the mechanical characterization of C103, a niobium-based alloy recognized for its high-temperature performance and good formability but facing challenges in oxidation resistance. The research employed tensile tests to assess the ductility and repeatability of C103 materials and conducted fatigue tests to analyze cyclic hardening effects. The findings reveal that C103 demonstrates excellent mechanical stability at elevated temperatures, aligning closely in behavior to conventionally manufactured counterparts, which supports its application in complex aerospace components. The results underscore the potential of C103 in the development of structural elements for propulsion systems, highlighting the role of appropriate coatings to mitigate oxidation under operational conditions. Overall, the study illustrates the viability of additively manufactured C103 for advanced applications in the aerospace sector, particularly in promoting highly intricate structures while maintaining performance integrity.
