| Abstract Scope |
As research continues for missions beyond low-Earth orbit, in-situ resource utilization (ISRU) methods are critical. For Lunar and Martian colonization, the ability to manufacture mechanical and structural components with local resources is essential. Ionic liquids (IL) are being studied at NASA Marshall Space Flight Center to harvest elemental metals from meteorites and regolith oxides. In this investigation, the effect of nickel and manganese additions in casting ductile iron using IL sourced iron (IL DI) was explored given ductile iron’s range of applications and performance as an as-cast alloy. Ingots were produced using commercial elements to simulate the use of IL iron with carbon from the by-products of the Bosch process, a life support system currently tested at MSFC. Samples were evaluated using phase transformations, microstructures, and hardness. Results showed the addition of nickel and manganese to IL DI is a viable means to produce a range of IL DI alloys. |
