Strain rate sensitivity of a Cu/AlO multi-layered thin film
Szilvia Kalácska, László PethÅ, 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…
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…
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…
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…
