Abstract Scope Refractory alloys have extraordinary resistance to heat, wear, and, with superior durability, are often the desired material for extreme environment applications on space craft, missiles, and hypersonic vehicles. Due to the difficulty and high cost of manufacturing complex shapes using refractory metals, utilization has been hampered in the most demanding applications. 3D printing has exhibited a superior shape producing capability. In this presentation, successful 3D printing of high quality Niobium C103 alloy components has been demonstrated. The properties of 3D printed Nb C103 were compared to equivalent wrought parts, including the effect of heat treatments. 3D “as-printed” microstructures were extremely stable and largely intact even after 2-hrs at 2900F. Superior properties of 3D printed Nb C103 were observed from room temperature to elevated temperature. A hypothesis for such stable microstructures is proposed. A case study of performance gain in sophisticated Nb C103 engineered hardware will also be presented.
