Incremental ECAP with Converging Billets [PDF]
Key Engineering Materials, 2013 Abstract: A new concept of incremental equal channel angular pressing (I-ECAP) with converging billets is proposed and simulated numerically. It follows a recently introduced process of ECAP with converging billets, in which the contact surface between converging billets plays the same role as a movable die wall in the output channel of classical ECAP ...

Severe plastic deformation of Al strips through equal multi and single channel angular pressing [PDF]
Scientific ReportsEqual channel multi-angular pressing (ECMAP) and equal channel angular pressing (ECAP) of Al-1050 strips were carried out. The ECMAP and ECAP load-displacement behavior, peak load, microhardness distribution maps, homogeneity, and average values were ...

X-ray Dark-Field Imaging for Improved Contrast in Historical Handwritten Literature
Journal of Imaging, 2022 If ancient documents are too fragile to be opened, X-ray imaging can be used to recover the content non-destructively. As an extension to conventional attenuation imaging, dark-field imaging provides access to microscopic structural object information ...

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021 Abstract Objectives The study aimed to assess the feasibility of recording electrically evoked compound action potentials (ECAPs) from the rat spinal cord. To achieve this, we characterized electrophysiological responses of dorsal column (DC) axons from electrical stimulation and quantified the relationship between ECAP and motor thresholds (ECAPTs and

Reconstructing the arrival direction of neutrinos in deep in-ice radio detectors
European Physical Journal C: Particles and Fields, 2023 In-ice radio detectors are a promising tool for the discovery of EeV neutrinos. For astrophysics, the implications of such a discovery will rely on the reconstruction of the neutrino arrival direction.

A Clinical Feasibility Study of Spinal Evoked Compound Action Potential Estimation Methods
Neuromodulation: Technology at the Neural Interface, EarlyView., 2021 Abstract Objectives Spinal cord stimulation (SCS) is a treatment for chronic neuropathic pain. Recently, SCS has been enhanced further with evoked compound action potential (ECAP) sensing. Characteristics of the ECAP, if appropriately isolated from concurrent stimulation artifact (SA), may be used to control, and aid in the programming of, SCS systems.

Investigation of Strain Inhomogeneity in Hexa-ECAP Processed AA7075 [PDF]
Archives of Metallurgy and Materials, 2021 Severe Plastic Deformation (SPD) techniques have been used by researchers for last three decades in order to obtain Ultra-Fine Grained (UFG) materials. Equal Channel Angular Pressing (ECAP) is preferred more than other SPD techniques thanks to its high ...

Effect of ECAP process on mechanical properties and microstructure of AA-6061 recycled chips [PDF]
Engineering and Technology Journal, 2023 The oxidation of aluminum machined chips makes successful recycling via the traditional re-melting technique difficult. A viable solution to this problem is to utilize solid-state recycling to transform aluminum machined chips directly into semi-finished

Effect of the power type of the general flow function in texture simulation of ECAP [PDF]
مواد نوین, 2021 Flow line model as an efficient model in ECAP process analysis is based on functions that evaluate the material plastic flow inside the die. Among the various flow functions, the general flow function has the highest ability in analyzing of ECAP process.
