Following recent conversations with friends and colleagues, Prof. Cláudio G. Schön, Prof. Ernst Kozeschnik and Dr. Johannes Österreicher, I have come to the conclusion that we should be more optimistic about the future of mankind, and of science, and physics in particular. This holds even when we take into account the geopolitical challenges of the … Continue reading Why I Remain Optimistic About the Future of Mankind
Ultrafine-grained (UFG) aluminium alloys are strong candidates for space structures: their dense grain-boundary network acts as sinks that absorb radiation-induced defects (more in our perspective review https://doi.org/10.1021/acsmaterialsau.5c00139). But that advantage only survives if the microstructure does — and in Low-Earth Orbit, sunlit components reach ~200 °C, right where severely deformed aluminium begins to recrystallise. The … Continue reading One-grain-at-a-time: how in situ EBSD rewrote sink-strength theory for space aluminium
