Features Thermomagnetic Behavior of CrMnFeCoNi High Entropy Alloy
The temperature dependences of magnetic susceptibility (Т) in the temperature range 300-900 K of CrMnFeCoNi high entropy alloy (HEA) with different thermal prehistory (after cutting samples from the bars (as-cast condition) and after annealing at Тh 800 and 950 С) were studied. It was shown that...

| Summary: | The temperature dependences of magnetic susceptibility (Т) in the temperature range 300-900 K of CrMnFeCoNi high entropy alloy (HEA) with different thermal prehistory (after cutting samples from the bars (as-cast condition) and after annealing at Тh 800 and 950 С) were studied. It was shown that the investigated alloys were characterized by a positive value , which increases with increasing annealing temperature. The temperature dependences of (Т) were decreasing with increasing T and characterized by irreversibility in a cycle of heating and cooling. Dependencies (Т) in the lower temperature range were analyzed in terms of the availability super paramagnetic particles (complexes) created a certain type of atoms placed in the non-magnetic or paramagnetic matrix with low Curie temperature and low effective localized magnetic moment. The model that links the formation of super paramagnetic particles with features structure of CrMnFeCoNi high entropy was considered. |
