Abstract Scope |
Remarkable attention has been drawn to the cryogenic industry, such as liquid hydrogen and aerospace. As a result, there is an increasing demand for the design of advanced alloys and the development of new manufacturing technologies to meet the specific requirements of ultra-cryogenic applications. CoCrNi medium entropy alloy has superior mechanical properties at cryogenic temperature, and SS316L is suitable metallic material for cryogenic industry applications. On the other hand, additive manufacturing (AM) technology exhibits distinctive microstructure, leading to improved mechanical properties. In this work, we manufactured AMed SS316L and CoCrNi medium entropy alloy and evaluated mechanical behavior at ultra-cryogenic temperature of 20K. Deformation mechanisms of AMed SS316L and CoCrNi medium entropy alloy at 20K will be revealed via multi-scale characterization analysis such as SEM/TEM, neutron diffraction, and metallurgical tools. |
