| Abstract Scope |
C103 has gained significant attention due to its high strength and temperature capabilities. Additive manufacturing can produce complex C103 components suitable for various fields, such as aerospace, due to its lower ductile-to-brittle transition temperature than other refractory metals. A challenge with C103 is its low oxidation resistance, which makes it susceptible to oxide formation during the various heating cycles involved in powder bed fusion, even in low-oxygen environments. This study aims to monitor the deterioration of C103 components made with PBF across 14 different print cycles. In addition, powder samples of each build are taken to monitor the powder’s reusability for subsequent usage. Part density, porosity, and oxygen content are analyzed across the various builds, along with changes in mechanical properties. Finally, a strain rate sensitivity analysis is performed to determine the effect of strain rate on wrought vs AM built samples through tensile and nanoindentation testing. |
