Moravcik, I.; Zelený, M.; Dlouhý, A.; Hadraba, H.; Moravcikova-Gouvea, L.; Papež, P.; Fikar, O.; Dlouhy, I.; Raabe, D.; Li, Z.: Impact of interstitial elements on the stacking fault energy of an equiatomic CoCrNi medium entropy alloy: theory and experiments. Science and Technology of Advanced Materials 23 (1), pp. 376 - 392 (2022)
Here the focus lies on investigating the temperature dependent deformation of material interfaces down to the individual microstructural length-scales, such as grain/phase boundaries or hetero-interfaces, to understand brittle-ductile transitions in deformation and the role of chemistry or crystallography on it.
In this project, we aim to enhance the mechanical properties of an equiatomic CoCrNi medium-entropy alloy (MEA) by interstitial alloying. Carbon and nitrogen with varying contents have been added into the face-centred cubic structured CoCrNi MEA.
