Atomistic deformation behavior of single and twin crystalline Cu nanopillars with preexisting dislocations
Won-Seok Ko, Alexander Stukowski, Raheleh Hadian +7
Molecular dynamics simulations are performed to investigate the role of a coherent Σ3 (111) twin boundary on the plastic deformation behavior of Cu nanopillars. Our work reveals th…
Structure and hardness of in situ synthesized nano-oxide strengthened CoCrFeNi high entropy alloy thin films
Subin Lee, Dominique Chatain, Christian H. Liebscher +1
In this study, we report on face-centered cubic structured CoCrFeNi high-entropy alloy thin films with finely dispersed nano-oxide particles which are formed by internal oxidation.…
Nanocrystalline equiatomic CoCrFeNi alloy thin films: Are they single phase fcc?
Maya Kini, Subin Lee, Alan Savan +9
The bulk quaternary equiatomic CoCrFeNi alloy is studied extensively in literature. Under experimental conditions, it shows a single-phase fcc structure and its physical and mechan…
Strain-Rate-Dependent Deformation Behavior of Ti29Zr24Nb23Hf24 High Entropy Alloys at Elevated and Room Temperature
Tangqing Cao, Wenqi Guo, Wang Lu +6
We investigate the strain-rate-dependent mechanical behavior and deformation mechanisms of a refractory high entropy alloy, Ti29Zr24Nb23Hf24 (at.%), with a single-phase body-center…
Faceting diagram for Ag segregation induced nanofaceting at an asymmetric Cu tilt grain boundary
Nicolas J. Peter, Maria J. Duarte, Christoph Kirchlechner +2
In this work, we experimentally establish the isothermal nanofacet evolution at an asymmetric tilt grain boundary in the Cu-Ag system using a diffusion couple approach. We investig…
Early stage phase separation of AlCoCr0.75Cu0.5FeNi high-entropy powder at the nanoscale
Nicolas J. Peter, Maria J. Duarte, Christian H. Liebscher +4
High entropy alloys are generally considered to be single phase material. This state is, however, typically a non-equilibrium state after fabrication at high cooling rates. Phase c…
