Abstract Scope |
Fe-36Ni Invar alloy is known to have enhanced ductility and tensile strength at cryogenic conditions and hence the alloy finds potential energy storage applications. However, in cryogenic conditions, the crystal-scale origins of these mechanical properties have not been probed for the want of appropriate characterization tools. Recent advancements in synchrotron testing capabilities enable the characterization of microstructure along with the mechanical behavior of individual crystals in polycrystalline metallic materials at low temperatures resembling service conditions. With the help of these advancements, here we track the evolution of grain-averaged lattice orientations and stress during in-situ mechanical loading of Fe-36Ni Invar alloy at 80K. These results are then compared with the material’s micromechanical response at room temperature. |
