Zhang, S. (author), Kwakernaak, C. (author), Tichelaar, F.D. (author), Sloof, W.G. (author), Kuzmina, M. (author), Herbig, M. (author), Raabe, D. (author), Brück, E. (author), Van der Zwaag, S. (author), Van Dijk, N.H. (author)The autonomous repair mechanism of creep cavitation during high-temperature deformation has been investigated in Fe-Au and Fe-Au-B-N alloys. Combined electron-microscopy techniques and atom probe tomography reveal how the improved creep properties result from Au precipitation within the creep cavities, preferentially formed on grain boundaries...journal article 2015

Zhang, S. (author), Langelaan, G. (author), Schut, H. (author), Brück, E. (author), Van der Zwaag, S. (author), Van Dijk, N.H. (author)Steels are among the most widely used construction materials as their mechanical properties can be tuned over a very wide range of desired combinations of strength formability and other properties. However, when exposed for long times to high temperatures steel components can exhibit premature and low-ductility creep fracture, which arises from...conference paper 2013
