Carrying out in-situ electron microscopic experiments of isochronal annealing at temperatures of 450 °C and 550 °C we could follow the structural changes in thin (40–50 nm thick) CoCrCuFeNi MPEA films. We observed that at temperatures 450 and 550 °C the first change in the structure is the martensitic transformation of the FCC to BCC phase. We have shown by EDS mapping of the transformed area that no compositional changes occur during this process and, specific for martensitic transformation orientation, relationships between the two phases are present. The changes occur after about 20 min annealing time at these temperatures. Longer anneals at the same temperatures lead to separation of components. Above 40 min annealing time at 450 °C voids appear in the film, Cr will be partly bonded to oxygen (impurity in the vacuum system) in the form of a thin surface oxide layer. The other components tend to form binary like compositions of Cu-Ni and Fe–Co pairs. We also estimated the diffusion coefficient at 450 °C in this alloy to be around ~6 × 10−19 m2/s. 2021 true true true false true false CLOSED 2026-04-25 false 8 0 8 8 0 8 8 7 8 8 8 8 8 8 0 0 8 8 8 8 0 3 3 Folyóiratcikk Journal Article 24 8 Könyvrészlet Chapter in Book 25 0 Könyv Book 23 0 Egyéb konferenciaközlemény Conference paper 31 0 Egyéb konferenciakötet Conference proceedings 32 0 Oltalmi formák Protection forms 26 0 Disszertáció Thesis 28 0 Egyéb Miscellaneous 29 0 Alkotás Achievement 22 0 Kutatási adat Research data 33 0 Folyóiratcikk Journal Article 24 0 0 0 Könyvrészlet Chapter in Book 25 0 0 0 Könyv Book 23 0 0 0 Egyéb konferenciaközlemény Conference paper 31 0 0 0 Egyéb konferenciakötet Conference proceedings 32 0 0 0 Oltalmi formák Protection forms 26 0 0 0 Disszertáció Thesis 28 0 0 0 Egyéb Miscellaneous 29 0 0 0 Alkotás Achievement 22 0 0 0 Kutatási adat Research data 33 0 0 0 2022 0 1 1 1 1 2023 0 2 2 2 2 2024 0 1 1 1 1 2025 0 4 4 4 4 D1 false 10001797 false false false 2021-01-21T09:13:38.812+0000 Fizika Doktori Iskola (ELTE / TTK);
