Verkin Institute for Low Temperature Physics and Engineering of the National Academy of Sciences of Ukraine popup.description2  Complex experimental researches of mechanical properties of low-temperature plastic deformation and microstructure of high-entropy coarse-grained Fe-Mn-Co-Cr alloys in the temperature range of 300 - 0.5 K have been carried out. The high cryogenic strength of Fe-Mn-Co-Cr alloys is reported, which is accompanied by a sufficiently high plasticity, which makes it possible to consider these materials as promising for cryogenic applications. It is established that high-pressure torsion at temperatures of 300 and 77 K would to obtain a nanostructured state with an average grain size of ~ 70 nm in the Fe40Mn40Co10Cr10 and Fe50Mn30Co10Cr10 alloys.
