Free, flexible and fast: orientation mapping using the multi-core and GPU-accelerated template matching capabilities in the python-based open source 4D-STEM analysis toolbox Pyxem
Niels Cautaerts, Phillip Crout, Håkon Wiik Ånes +4
This work presents the new template matching capabilities implemented in Pyxem, an open source Python library for analyzing four-dimensional scanning transmission electron microsco…
Microstructure, grain boundary evolution and anisotropic Fe segregation in (0001) textured Ti thin films
Vivek Devulapalli, Marcus Hans, Prithiv T. Sukumar +3
The structure and chemistry of grain boundaries (GBs) are crucial in determining polycrystalline materials' properties. Faceting and solute segregation to minimize the GB energy is…
Dual phase patterning during a congruent grain boundary phase transition in elemental copper
Lena Frommeyer, Tobias Brink, Rodrigo Freitas +3
The phase behavior of grain boundaries can have a strong influence on interfacial properties. Little is known about the emergence of grain boundary phases in elemental metal system…
Towards Superior High Temperature Properties in Low Density AlCrFeNiTi Compositionally Complex Alloys
Silas Wolff-Goodrich, Sebastian Haas, Uwe Glatzel +1
Three novel precipitation strengthened bcc alloys which exhibit a smooth microstructural gradient with composition have been fabricated in bulk form by induction casting. All three…
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.…
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$…
Aluminum depletion induced by complex co-segregation of carbon and boron in a Σ 5 [3 1 0] bcc-iron grain boundary
Ali Ahmadian, Daniel Scheiber, Xuyang Zhou +4
The local variation of grain boundary atomic structure and chemistry caused by segregation of impurities influences the macroscopic properties of poylcrystalline materials. Here, t…
