Pei, Z.; Zhang, S.; Lei, Y.; Zhang, F.; Chen, M.: Decoupling between Shockley partials and stacking faults strengthens multiprincipal element alloys. Proceedings of the National Academy of Sciences of the United States of America 118 (51), e2114167118 (2021)
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.
