Revealing the Atomic-Scale Structure of the Copper Sulfuric Acid Interface
Lalith Kumar Bhaskar, Sung-Gyu Kang, Oliver R. Waszkiewicz +7
Corrosion originates from atomistic reactions occurring at dynamic solid liquid interfaces however, direct experimental observation of these reactions has remained elusive due to t…
Defect dependent dynamic nanoindentation hardness of copper up to 25 000 s-1
Hendrik Holz, Lalith Kumar Bhaskar, Tobias Brink +4
Metals exhibit an upturn in strength at strain rates of approximately 1000 s-1 - 3000 s-1, governed by rapid dislocation multiplication, interactions and storage. This phenomenon i…
Filling a gap in materials mechanics: Nanoindentation at high constant strain rates upto
Lalith Kumar Bhaskar, Dipali Sonawane, Hendrik Holz +12
A central focus in high strain rate research is understanding the dynamic behavior of materials at strain rates where a strength upturn is observed. While strength upturns at strai…
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…
Probing Elastic Isotropy in Entropy Stabilized Transition Metal Oxides: Experimental Estimation of Single Crystal Elastic Constants from Polycrystalline Materials
Lalith Kumar Bhaskar, Niraja Moharana, Hendrik Holz +3
Single Crystal Elastic Constants (SECs) are pivotal for understanding material deformation, validating interatomic potentials, and enabling crucial material simulations. The entrop…
High Strain Rate Compressive Deformation Behavior of Nickel Microparticles
Bárbara Bellón, Lalith Kumar Bhaskar, Tobias Brink +5
Understanding the mechanical properties of metals at extreme conditions is essential for the advancement of miniaturized technologies. As dimensions decrease, materials will experi…
