Recrystallisation phenomena in an ultrafine-grained Al-Mg-Si alloy revealed by correlative in situ EBSD and TEM heating
Moritz Theissing, Sandra Gonzaga, Patrick Willenshofer +5
Ultrafine-grained (UFG) aluminium alloys are promising lightweight structural materials for space applications, where a high grain-boundary density can act as sinks for irradiation…
CuCrZr heat-sink irradiation performance reveals new challenges for thermonuclear fusion reactors
Thomas Barzic, Anna-Carina Seitlinger, Christoph Frühwirth +10
Commercial fusion energy requires materials that survive intense neutron bombardment whilst extracting extreme heat loads for conversion to electricity. The CuCrZr alloy, the leadi…
Direct nanoscale observation of melting and solute redistribution in a hypoeutectic Al-Cu alloy with STEM
Martin Hasenburger, Rostislav Daniel, Phillip Dumitraschkewitz +3
Melting and solidification of eutectic systems are classical topics in physical metallurgy, yet the mechanisms at nanoscale are less investigated, due to experimental limitations i…
Local electrochemical characterization of active Mg-Fe materials: from pure Mg to Mg50-Fe composites
Noémie Ott, Aurélien Tournier Fillon, Oliver Renk +4
This study demonstrates the applicability of the scanning electrochemical nanocapillary (SEN) technique to characterize the local surface reactivity of active systems, such as Mg-b…
Radiation-resistant aluminium alloy for space missions in the extreme environment of the solar system
Patrick D. Willenshofer, Matheus A. Tunes, Ho T. Vo +5
Future human-based exploration of our solar system requires the invention of materials that can resist harsh environments. Age-hardenable aluminium alloys would be attractive candi…
Precipitation in lean Mg-Zn-Ca alloys
R. E. Schaublin, M. Becker, M. Cihova +6
While lean Mg-Zn-Ca alloys are promising materials for temporary implants, questions remain on the impact of Zn and Ca. In this context, the precipitation in Mg-1.5Zn-0.25Ca (ZX20,…
MEMS-based in situ electron-microscopy investigation of rapid solidification and heat treatment on eutectic Al-Cu
Phillip Dumitraschkewitz, Matheus A. Tunes, Cameron R. Quick +5
The solidification behavior of a eutectic AlCu specimen is investigated via in situ scanning transmission electron microscope (STEM) experiments. Solidification conditions are vari…
A contamination-free electron-transparent metallic sample preparation method for MEMS experiments with in situ S/TEM
Matheus A. Tunes, Cameron Quick, Lukas Stemper +5
Microelectromechanical systems (MEMS) are currently supporting ground-breaking basic research in materials science and metallurgy as they allow in situ experiments on materials at…
