“…Consequently, the ARBed Cu/Ti billets were obtained in different passes. Then, to achieve the preparation of Cu–Ti alloys with high compositional homogeneity and prepare for physical phase modulation, [ 2,19 ] ARBed Cu/Ti billets were held at 800 °C for 10 h to carry out an initial diffusion heat treatment in vacuum, followed by water cooling and 20% deformation at room temperature, and then held at 800 °C for different times to complete the secondary diffusion heat treatment in vacuum. Finally, ARB‐DDed Cu–Ti alloys were obtained by water quenching to room temperature.…”

“…Combined with the results of the previous study, it can be seen in Figure 11 that residues of small‐size intermetallic compounds are still present in the 0.3/0.03‐4‐ARB5‐13‐treated alloy (Figure 11a). [ 2 ] At this moment, the residual segregation index is 0.36. When the diffusion heat treatment time is extended to 14 h, intermetallic compounds disappear (Figure 11b).…”

“…It has been proved to be an advanced and effective way to achieve the homogeneity of composition. [ 2 ] In this process, the thickness ratio of initial components, degree of deformation, temperature, and time are all important factors that affect the elemental diffusion behavior. Due to multiple influencing factors and the different influence degrees, the coupling effect makes it difficult to the synergistic control of the ARB and DD process and it leads to an extremely difficult control of elemental diffusion.…”

Simultaneous monitoring of electrophysiology and magnetic resonance imaging (MRI) could guide the innovative diagnosis and treatment of various neurodegenerative diseases that were previously impossible. However, this technique is difficult because the existing metal‐based implantable neural interface for electrophysiology is not free from signal distortions due to its intrinsic magnetic susceptibility while performing an MRI of the implanted area of the neural interface. Moreover, brain tissue heating from neural implants generated by the radiofrequency field from MRI poses potential hazards for patients. Previous studies with soft polymer‐based electrode arrays that overcome this issue provided relatively suitable MRI compatibility but did not guarantee high‐resolution electrophysiological signal acquisition and stimulation performance. Here, we introduce MRI compatible, optically transparent flexible implantable device capable of electrophysiological multichannel mapping and electrical stimulation. Using the device, we confirmed neuropathic pain (NP) relief with a 30‐channel electrophysiological mapping of the somatosensory area before and after motor cortex stimulation (MCS) in allodynia rats after noxious stimulation. Additionally, we demonstrated artifact‐free manganese‐enhanced MRI of dramatic relief of pain‐related region activity by MCS. Furthermore, artifact‐free optogenetics with transgenic mice was also investigated by recording light‐evoked potentials. These results suggested a promising neuro‐prosthetic for analyzing and modulating spatiotemporal neurodynamic without MRI or optical modality resolution constraints.This article is protected by copyright.

“…The application of cold rolling treatments can effectively reduce the grain size of the alloy and enhance the density of dislocations, leading to a significant improvement in its strength. Subsequent aging treatments can promote the precipitation of the strengthened phase and effectively improve the strength and electrical conductivity of the alloy [11][12][13]. Fu et al [11] showed that the tensile strength of a Cu-Cr-Zr alloy increased with the increase of the reduction rate during thermo-mechanical treatment.…”

In this paper, a Cu-Ni-Cr alloy was prepared by adding a Ni-Cr intermediate alloy to copper. The effects of the cold rolling reduction rate on the microstructure and properties of the Cu-1.16Ni-0.36Cr alloy after thermo-mechanical treatment were studied. The results show that the tensile strength of the alloy increased while the electrical conductivity slightly decreased with an increase of the cold rolling reduction rate. At a rolling strain of 3.2, the tensile strength was 512.0 MPa and the conductivity was 45.5% IACS. At a rolling strain of 4.3, the strength further increased to 536.1 MPa and the conductivity decreased to 41.9% IACS. The grain size and dislocation density decreased with an increase of the reduction rate in the thermo-mechanical treatment. However, when the rolling strain reached 4.3, the recrystallization degree of the alloy increased due to an accumulation of the dislocation density and deformation energy, resulting in a slight increase in the grain size and a decrease in the dislocation density. The texture strength of the brass increased due to the induced shear band, with an increase of the cold rolling reduction rate. The reduction rate promoted a uniform distribution of nano-scale Cr precipitates and further enhanced the strength via precipitation strengthening.
