Design, Manufacture and Prospects of Heterostructured Materials

cMat, Volume 2, Issue 4, December 2025.
ABSTRACT Heterostructured materials, characterized by distinct microstructures and mechanical properties across different micro‐regions, have consistently demonstrated their ability to effectively mitigate the strength‐ductility trade‐off in structural materials.

Optimizing the ECAP processing parameters of pure Cu through experimental, finite element, and response surface approaches

Reviews on Advanced Materials Science, 2023
The main aim of the current work is to investigate the effect of equal channel angular pressing (ECAP) processing parameters, namely, number of passes, ECAP die angle, route type, and processing temperature on the mechanical and electrical properties of ...

The cochlear apex demystified: Implications from synchrotron radiation phase‐contrast imaging and microscopy for cochlear implantation

Journal of Anatomy, Volume 247, Issue 6, Page 1283-1296, December 2025.
This study is the first to present the detailed cellular organization and three‐dimensional (3D) tonotopic arrangement of the human organ of Corti, spiral ganglion, and central modiolus using synchrotron radiation phase‐contrast imaging (SR‐PCI) with matched histological cross‐sections.

The Structural Refinement of Commercial‐Purity Copper Processed by Equal Channel Angular Pressing with Low Strain Amplitude

Advanced Engineering Materials, Volume 27, Issue 21, November 2025.
Equal channel angular pressing of commercial pure copper under low strain amplitude (≈0.48) induces concurrent continuous and localized discontinuous dynamic recrystallization, forming a duplex structure influenced by strain heterogeneity and recovery. Moderate hardening after 4–12 passes results from progressive high‐angle grain boundary formation via

Quasi-Stationary Strength of ECAP-Processed Cu-Zr at 0.5 T_m

Metals, 2019
The influence of the grain structure on the tensile deformation strength is studied for precipitation-strengthened Cu-0.2%Zr at 673K. Subgrains and grains are formed by equal channel angular pressing (ECAP) and annealing.

Linking Heat Treatment to Plastic Deformation in Pearlitic Steels Through Mesoscale Modeling

Advanced Engineering Materials, Volume 27, Issue 21, November 2025.
Surface wear on rail and wheel steels results from surface deformation during use. This research uses mathematical models to forecast the plastic behavior of pearlitic steels, connected to the microstructure formed during heat treatment. While the cooling rate impacts the steels’ strength, the size of prior austenite grains and blocks does not ...

Characterization of Diffusion‐Creep Olivine Fabric and Its Identification in Natural Peridotite: Repeated Pure Shear and Equal‐Channeling Angular Pressing Tests

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract We performed repeated pure shear and equal‐channel angular pressing tests on Fe‐free olivine +10 or 20 vol% diopside aggregates to investigate the characteristics of crystallographic preferential orientation (CPO) development in olivine during diffusion creep.

Deformation Behavior of La2O3‐Doped Copper during Equal Channel Angular Pressing

Advanced Engineering Materials, Volume 27, Issue 20, October 2025.
By additions of strengthening elements and/or structure optimization, the mechanical properties of copper can be increased while keeping favorable electric conductivity. By combining addition of La2O3 and processing by equal channel angular pressing, substructure development is achieved, leading to increase in microhardness to more than double the ...

Joining UFG Copper by Means of the W2Mi Machine [PDF]

Archives of Metallurgy and Materials
Joining metals with ultra-fine grains (UFG) is very difficult. UFG metals have a grain size of less than 1 µm. Exceeding the recrystallization temperature causes the growth of ultra-fine grains and degradation of the material’s mechanical properties. The

Long‐Term Cochlear Implant Sensitivity in Patients With Far Advanced Otosclerosis

The Laryngoscope, Volume 135, Issue 10, Page 3885-3892, October 2025.
This study aimed to evaluate mid‐ and long‐term cochlear implant fitting in otosclerosis patients compared to a control group. It suggested significant tissue remodeling at the cochlear apex in otosclerosis patients, likely increasing resistance to electrical currents delivered by the implant.
