Hello, fellow researchers, I am currently studying the phase stability of a CrCoFeMnNi high entropy alloy subjected to high temperatures (1050 °C). My recent XRD analyses revealed non-symmetrical FCC peaks at approximately 43 and 50 degrees, with noticeable shoulder peaks. These shoulder peaks suggest the potential presence of FCC phases with different d-spacings in the same sample. This observation persists despite various attempts at confirming the phases through search and match techniques, which also indicate these as FCC-related peaks. Has anyone observed similar phenomena in high entropy alloys or other complex systems? Could there be a plausible explanation for the coexistence of multiple FCC lattices within the same material under these conditions? Any insights into phase transformations or segregation behaviours at high temperatures in such alloys would be greatly appreciated. Thank you in advance for your contributions!
