A research team led by Dr. Jeong Min Park from the Korea Institute of Materials Science (KIMS) has developed a new high-performance metal 3D-printed alloy tailored for space environments. Collaborating with professors from Gyeongsang National University and POSTECH, the team added carbon to CoCrFeMnNi alloy and used the Laser Powder Bed Fusion method for processing. The alloy exhibited exceptional mechanical performance at extreme cryogenic temperatures, showing potential for space exploration and other extreme environment applications. With a combination of tensile strength and ductility that exceeded carbon-free alloys by over 140% at cryogenic temperatures, this technology offers a breakthrough in developing new alloys for extreme environments.
The technology allows for fine-controlling of microstructure through additive manufacturing, making it ideal for complex components used in space exploration rockets and turbine nozzles. The technology enhances performance and extends the lifespan of parts used in space and other extreme environments. Dr. Jeong Min Park, the project leader, highlighted the significance of this research in improving the performance of parts used in space launch vehicles.
Funded by KIMS, the research findings were published in the journal “Additive Manufacturing.” The research team plans to continue studying to enhance the commercialization potential of this technology and further verify its performance in extreme environments. KIMS, a non-profit research institute specializing in comprehensive materials technologies in Korea, has played a significant role in advancing materials science and technology in the country.
