Phase-field modeling of elastically driven abnormal grain growth
Yazhuo Liu, Yin Zhang, Kunqing Ding +6
Grain-refined metals typically exhibit high strength, yet their engineering applications are often constrained by grain coarsening under thermo-mechanical loading. Recent experimen…
Machine learning of twin/matrix interfaces from local stress field
Javier F. Troncoso, Yang Hu, Nicolo M. della Ventura +3
Twinning is an important deformation mode in plastically deformed hexagonal close-packed materials. The extremely high twin growth rates at the nanoscale make atomistic simulations…
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…
In situ atomic force microscopy depth-corrected 3-dimensional focused ion beam based time-of-flight secondary ion mass spectroscopy: spatial resolution, surface roughness, oxidation
Lex Pillatsch, Szilvia Kalácska, Xavier Maeder +1
Atomic force microscopy (AFM) is a well-known tool for studying surface roughness and to collect depth information about features on the top atomic layer of samples. By combining s…
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…
The effect of δ-hydride on the micromechanical deformation of Zircaloy-4 studied by in situ high angular resolution electron backscatter diffraction
Siyang Wang, Szilvia Kalácska, Xavier Maeder +3
Zircaloy-4 is used extensively as nuclear fuel cladding materials and hydride embrittlement is a major failure mechanism. To explore the effect of δ-hydride on plastic deformation…
The role of β-titanium ligaments in the deformation of dual phase titanium alloys
Tea-Sung Jun, Xavier Maeder, Ayan Bhowmik +4
Multiphase titanium alloys are critical materials in high value engineering components, for instance in aero engines. Microstructural complexity is exploited through interface engi…
