Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

Advanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Recrystallization in an Mg-Nd alloy processed by high-pressure torsion: a calorimetric analysis

Journal of Materials Research and Technology, 2020
Differential scanning calorimetry (DSC) was used to evaluate the recrystallization temperature and activation energy for an Mg-1.43Nd (wt.%) alloy after severe plastic deformation by high-pressure torsion (HPT) at room temperature up to 10 turns.

Nanostructural formation by severe plastic deformation

Metalurgija, 2005
Istraživao se utjecaj snažnih plastičnih deformacija na strukturalna, mehanička i plastična svojstva ARMCO-željeza u postupku prešanja s istiskivanjem kroz jednake kanale (ECAP) postavljene pod nekim kutom. Primjenjivale su se također i matematičke simulacije područja naprezanja i temperaturnih područja.

A Topology Optimization Framework for the Inverse Design of Nonlinear Mechanical Metamaterials

Advanced Engineering Materials, EarlyView.
This work uses topology optimization to design unit cells for mechanical metamaterials with a prescribed nonlinear stress–strain response. The framework adds contact and postbuckling modeling to synthesize microstructures for three highly nonlinear responses, including pseudoductile behavior, monostable with snap‐through buckling, and bistable ...

Influence of severe plastic deformation on the microstructure and hardness of a CoCrFeNi high-entropy alloy: A comparison with CoCrFeNiMn

Materials Characterization, 2019
The evolution of microstructure and hardness in a CoCrFeNi high-entropy alloy (HEA) processed by severe plastic deformation (SPD) was studied. SPD-processing was carried out using a high-pressure torsion (HPT) technique up to twenty turns at room ...

Combinatorial Synthesis of Next Generation Water‐Soluble Quaternized N‐Halamine Oligomers with Long‐Lasting Antiviral Properties

Advanced Functional Materials, EarlyView.
A combinatorial library of dual‐functional antiviral oligomers incorporating N‐halamine and quaternary ammonium functionalities is developed for long‐lasting antiviral activity. The lead materials exhibit rapid and durable antiviral activity against SARS‐CoV‐2 variants and influenza H1N1, with 4 to 5 log reduction in viral copies at 5 mg mL−1 ...
