A team from Korea Institute of Materials Science (KIMS), in collaboration with Kyungpook National University and POSTECH, has created a high-performance 3D-printed metal alloy designed for the extreme conditions of space. This advanced alloy demonstrates 140% improvement in strength and flexibility compared to standard materials, making it ideal for components in spacecraft and other challenging environments. The alloy, based on a CoCrFeMnNi material with added carbon, is crafted using Laser Powder Bed Fusion (LPBF), a 3D printing technique that fuses metal powder with laser precision. By carefully controlling carbon content, researchers embedded nanoscale carbides within the alloy, significantly enhancing its durability at cryogenic temperatures as low as -196°C. Tests reveal the alloy's impressive performance, doubling in tensile strength at 77K (cryogenic temperatures) compared to room temperature. This innovation paves the way for stronger, longer-lasting space components, such as rocket fuel injectors and turbine nozzles, that endure high-stress, low-temperature conditions.
