Thermal response of an in-situ STEM MEMS chip under rapid pulse heating
Phillip Dumitraschkewitz, Thomas Kremmer
In-situ rapid solidification studies demand measurements of thermal histories with high temporal resolution. We present a simple, effective setup to quantify the cooling response o…
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…
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…
Size-dependent surface energies of Au nanoparticles
D. Holec, P. Dumitraschkewitz, F. D. Fischer +1
Motivated by often contradictory literature reports on size dependence of surface energy of gold nanoparticles, we performed an atomistic study combining molecular dynamics and \te…
