Advancing in situ hydrogen embrittlement studies through an integrated charging cell for SEM micromechanical testing
Lavakumar Bathini, Guillaume Kermouche, Sergio Sao-Joao +2
A comprehensive understanding of hydrogen-deformation interactions at the microscale is essential for revealing hydrogen embrittlement mechanisms. In situ micromechanics with simul…
Remanent crustal strain on Mars in non-poikilitic olivine of NWA 7721
Yaozhu Li, Szilvia Kalácska, Phil McCausland +5
We present a multiscale microstructural analysis of olivine from the non-poikilitic lithology of the poikilitic shergottite NWA 7721, using dark-field X-ray microscopy (DFXM), elec…
Investigation of quasi-cleavage in a hydrogen charged maraging stainless steel
Jolan Bestautte, Szilvia Kalácska, Denis Béchet +2
Slow strain rates tests (SSRT) were conducted on hydrogen-containing specimens of PH13-8Mo maraging stainless steel. Hydrogen-assisted subcritical quasi-cleavage cracking was shown…
Statistical analysis of dislocation cells in uniaxially deformed copper single crystals
Sándor Lipcsei, Szilvia Kalácska, Péter Dusán Ispánovity +3
The dislocation microstructure developing during plastic deformation strongly influences the stress-strain properties of crystalline materials. The novel method of high resolution…
Anomalous High Strain Rate Compressive Behavior of Additively Manufactured Copper Micropillars
Rajaprakash Ramachandramoorthy, Szilvia Kalácska, Gabriel Poras +7
Microscale dynamic testing is vital to the understanding of material behavior at application relevant strain rates. However, despite two decades of intense micromechanics research,…
3D HR-EBSD characterization of the plastic zone around crack tips in tungsten single crystals at the micron scale
Szilvia Kalácska, Johannes Ast, Péter Dusán Ispánovity +2
High angular resolution electron backscatter diffraction (HR-EBSD) was coupled with focused ion beam (FIB) slicing to characterize the shape of the plastic zone in terms of geometr…
Investigation of geometrically necessary dislocation structures in compressed Cu micropillars by 3-dimensional HR-EBSD
Szilvia Kalácska, Zoltán Dankházi, Gyula Zilahi +4
Mechanical testing of micropillars is a field that involves new physics, as the behaviour of materials is non-deterministic at this scale. To better understand their deformation me…
Comparison of the dislocation density obtained by HR-EBSD and X-ray profile analysis
Szilvia Kalácska, István Groma, András Borbély +1
Based on the cross correlation analysis of the Kikuchi diffraction patterns high-resolution EBSD is a well established method to determine the internal stress in deformed crystalli…
