Postma, J.I. (author), Ferrari, A. (author), Bottger, A.J. (author)Surface compositions play a predominant role in the efficiency and lifetime of membranes and catalysts. The surface composition can change during operation due to segregation, thus controlling and predicting the surface composition is essential. Computational modelling can aid in predicting alloy stability, along with designing surface alloys...journal article 2023

Fu, Y. (author), Fang, H. (author), Monaco, F. (author), Cloetens, P. (author), Tichelaar, F.D. (author), van Meel, J.G. (author), Brück, E.H. (author), van der Zwaag, S. (author), van Dijk, N.H. (author)Constant stress creep experiments at 550 °C were performed on a high-purity Fe-3Au-4W (wt.%) ternary alloy with about 1 at.% supersaturation for Au and W in order to study self healing of grain-boundary cavities by both Au-rich and W-rich precipitates. Using synchrotron X-ray nano-tomography, the development of the creep cavities and the...journal article 2022

Zhao, M. (author), Brouwer, J.C. (author), Sloof, W.G. (author), Bottger, A.J. (author)Ternary alloys have been developed for a wide range of applications and surface segregation of ternary alloys has a decisive impact on their performance. Different from binary alloys, in which surface energy is usually the dominant factor, the interaction between solute elements has a noticeable effect on the surface segregation behavior of...journal article 2020
