Аннотация
In this paper, the results of study of the AlCoCrFeNi high-entropy alloy by means of atom probe tomography are presented. Two phases were found, one enriched in Fe and Cr and the other enriched in Ni and Al. Owing to the complex surface morphology and spatial configuration of the phases, they were analyzed by various statistical methods. The Fe-Cr phase has a honeycomb structure that contains Co particles with the characteristic size of similar to 10 nm. The enrichment of the cell boundaries in Fe and Cr atoms reaches 50 at %. In turn, the Al-Ni phase is enriched in each of these elements up to 30 at % and contains nanoscale precipitates of Fe and Cr atoms. The volume density of these clusters is similar to 5 x 10(22) cm(-3).
