“…In a recently developed group of Fe--Mn-Co-Al-C alloys, the alloy with 10 mass% Co showed high mechanical properties: yield strength of 1.59 GPa and ultimate tensile strength of 1.65 GPa with 10% tensile ductility. 53 However, that alloy was still rich in Fe (50.2 mass%). In the present work, we consider Fe-Mn-Ni-Al-C and Fe-Mn-Ni-Co-Al-C alloys having nearly equiatomic 3dLTM content as another family of high-entropy alloys based on a Fe-Mn-Al-C industrial steel.…”

High entropy alloys (multiprinciple element alloys) were produced by dilution of the base component in a Fe–Mn–Al–C alloy. The studied Fe–Mn–Ni–Al–C and Fe–Mn–Ni–Co–Al–C alloys were treated thermally and mechanically. These alloys were studied by X-ray diffractometry and electron microscopy, while mechanical properties were tested by mechanical loading. A dual-phase cF4 and cP2 structure was formed. The alloys showed high-hardness values and high-strain hardening ability but when hot rolled exhibited precipitation of carbides. These alloys are considered to be model alloys for the development of future high-entropy alloys based on industrial steels.
