Micromechanics reveal strain rate dependent transition between dislocation mechanisms in a dual phase high entropy alloy
Szilvia Kalácska, Amit Sharma, Rajaprakash Ramachandramoorthy +8
An equimolar NiCoFeCrGa high entropy alloy having dual-phase homogeneous components was studied, where the constituent phases exhibit distinct mechanical properties. Micropillars w…
Strain rate sensitivity of a Cu/AlO multi-layered thin film
Szilvia Kalácska, László Pethő, Guillaume Kermouche +2
To study the size and strain rate dependency of copper polycrystalline microstructures, a multi-layered copper/AlO thin film was deposited on a Si substrate using a hybrid…
On identifying dynamic length scales in crystal plasticity
Dénes Berta, David Kurunczi-Papp, Lasse Laurson +1
Materials are often heterogeneous at various length scales, with variations in grain structure, defects, and composition which has a strong influence on the emergent macroscopic pl…
Avalanche Dynamics and the Effect of Straining in Dislocation Systems with Quenched Disorder
Dénes Berta, Barna Mendei, Péter Dusán Ispánovity
The plastic deformation of crystalline and other heterogeneous materials often manifests in stochastic intermittent events indicating the criticality of plastic behavior. Previous…
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…
Irradiation-induced strain localization and strain burst suppression investigated by microcompression and concurrent acoustic emission experiments
Dávid Ugi, Gábor Péterffy, Sándor Lipcsei +4
Plastic deformation of microsamples is characterised by large intermittent strain bursts caused by dislocation avalanches. Here we investigate how ion irradiation affects this phen…
Dynamic Length Scale and Weakest Link Behavior in Crystal Plasticity
Dénes Berta, Gábor Péterffy, Péter Dusán Ispánovity
Plastic deformation of heterogeneous solid structures is often characterized by random intermittent local plastic events. On the mesoscale this feature can be represented by a spat…
