At the phenomenological level, a theoretical analysis of the concentration dependence of the thermalresistance coefficient (βТ), strain sensitivity coefficient (SC) and Curie temperature (ΘС) for film high-entropysolid solutions based on Fe, Ni, Co, Cu, Cr was carried out. It was found that βТ of 4- and 5-component filmalloys varies within (1,00-1,75).10 – 3 К – 1, and SC – (4.00-5.75) units, which corresponds well to the data forsingle-component metal films. It was concluded that, from the point of view of βТ and SC, solid solutions ofHEA have no advantage over single-component films, but they can be more effective sensitive elements ofvarious sensors due to the thermal stability of the phase composition. The situation is different in the caseof ΘС, when ΘС can decrease or increase by 350-400 K. Since the information about the HEA domain structureis limited, we assume that the domain structure is realized in magnetic granules based on Cu atoms. But inthis case, the size effect can cause a ΘС decrease, which, unfortunately, we could not take into account withinour concept of additivity of the physical quantities of the solid solution of HEA [ABSTRACT FROM AUTHOR] |
