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

open access: yesAdvanced 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

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

open access: yesAdvanced 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 ...

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

open access: yesArchives 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

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

open access: yesJournal 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.

S-stars in the Galactic center and hypervelocity stars in the Galactic halo: two faces of the tidal breakup of stellar binaries by the central massive black hole?

open access: yes, 2013
In this paper, we investigate the link between the hypervelocity stars (HVSs) discovered in the Galactic halo and the S-stars moving in the Galactic center (GC), under the hypothesis that they are both the products of the tidal breakup of the same ...

Development of Combined Opto-Acoustical Sensor Modules

open access: yes, 2011
The faint fluxes of cosmic neutrinos expected at very high energies require large instrumented detector volumes. The necessary volumes in combination with a sufficient shielding against background constitute forbidding and complex environments (e.g.
