Atomistic deformation behavior of single and twin crystalline Cu nanopillars with preexisting dislocations
Won-Seok Ko, Alexander Stukowski, Raheleh Hadian +7
Molecular dynamics simulations are performed to investigate the role of a coherent Σ3 (111) twin boundary on the plastic deformation behavior of Cu nanopillars. Our work reveals th…
Automated crystal orientation mapping by precession electron diffraction assisted four-dimensional scanning transmission electron microscopy (4D-STEM) using a scintillator based CMOS detector
Jiwon Jeong, Niels Cautaerts, Gerhard Dehm +1
The recent development of electron sensitive and pixelated detectors has attracted the use of four-dimensional scanning transmission electron microscopy (4D-STEM). Here, we present…
Structure and hardness of in situ synthesized nano-oxide strengthened CoCrFeNi high entropy alloy thin films
Subin Lee, Dominique Chatain, Christian H. Liebscher +1
In this study, we report on face-centered cubic structured CoCrFeNi high-entropy alloy thin films with finely dispersed nano-oxide particles which are formed by internal oxidation.…
Nanocrystalline equiatomic CoCrFeNi alloy thin films: Are they single phase fcc?
Maya Kini, Subin Lee, Alan Savan +9
The bulk quaternary equiatomic CoCrFeNi alloy is studied extensively in literature. Under experimental conditions, it shows a single-phase fcc structure and its physical and mechan…
Investigation of the orientation relationship between nano-sized G-phase precipitates and austenite with scanning nano-beam electron diffraction using a pixelated detector
Niels Cautaerts, Edgar F. Rauch, Jiwon Jeong +2
Scanning nano-beam electron diffraction with a pixelated detector was employed to investigate the orientation relationship of nanometer sized, irradiation induced G-phase (MNi$…
Strain-Rate-Dependent Deformation Behavior of Ti29Zr24Nb23Hf24 High Entropy Alloys at Elevated and Room Temperature
Tangqing Cao, Wenqi Guo, Wang Lu +6
We investigate the strain-rate-dependent mechanical behavior and deformation mechanisms of a refractory high entropy alloy, Ti29Zr24Nb23Hf24 (at.%), with a single-phase body-center…
