Nanomaterials by severe plastic deformation: review of historical developments and recent advances

Publication Type: Academic Journal

Source(s): Materials Research Letters, Vol 10, Iss 4, Pp 163-256 (2022)

Abstract: Severe plastic deformation (SPD) is effective in producing bulk ultrafine-grained and nanostructured materials with large densities of lattice defects. This field, also known as NanoSPD, experienced a significant progress within the past two decades. B...

Exchange Bias Demonstrated in Bulk Nanocomposites Processed by High-Pressure Torsion

Publication Type: Academic Journal

Source(s): Nanomaterials, Vol 13, Iss 344, p 344 (2023)

Abstract: Ferromagnetic (Fe or Fe20Ni80) and antiferromagnetic (NiO) phases were deformed by high-pressure torsion, a severe plastic deformation technique, to manufacture bulk-sized nanocomposites and demonstrate an exchange bias, which has been reported predomi...

Sampling the Cu–Fe–Co phase diagram by severe plastic deformation for enhanced soft magnetic properties

Publication Type: Academic Journal

Source(s): Journal of Materials Research and Technology, Vol 12, Iss , Pp 1235-1242 (2021)

Abstract: Initial powder mixtures of Cu, Fe and Co are exposed to severe plastic deformation by high-pressure torsion to prepare solid solutions. A broad range of compositions is investigated, whereas this study aims at the synthesis of soft magnetic materials a...

On the magnetic nanostructure of a Co–Cu alloy processed by high-pressure torsion

Publication Type: Academic Journal

Source(s): Journal of Science: Advanced Materials and Devices, Vol 6, Iss 1, Pp 33-41 (2021)

Abstract: In this study, a preparation route of Co–Cu alloys with soft magnetic properties by high-pressure torsion deformation is introduced. Nanocrystalline, supersaturated single-phase microstructures are obtained after deformation of Co–Cu alloys, which are ...

Manufacturing of Textured Bulk Fe-SmCo5 Magnets by Severe Plastic Deformation

Publication Type: Academic Journal

Source(s): Nanomaterials, Vol 12, Iss 963, p 963 (2022)

Abstract: Exchange-coupling between soft- and hard-magnetic phases plays an important role in the engineering of novel magnetic materials. To achieve exchange coupling, a two-phase microstructure is necessary. This interface effect is further enhanced if both ph...

Exchange Bias Demonstrated in Bulk Nanocomposites Processed by High-Pressure Torsion.

Publication Type: Academic Journal

Source(s): Nanomaterials (2079-4991); Jan2023, Vol. 13 Issue 2, p344, 19p

Soft Magnetic Properties of Ultra-Strong and Nanocrystalline Pearlitic Wires

Publication Type: Academic Journal

Source(s): Nanomaterials, Vol 12, Iss 23, p 23 (2021)

Abstract: The paper describes the capability of magnetic softening of a coarse-grained bulk material by a severe deformation technique. Connecting the microstructure with magnetic properties, the coercive field decreases dramatically for grains smaller than the ...

In situ AC-hysteresis measurements of SPD-processed Cu20(Fe15Co85)80

Publication Type: Academic Journal

Source(s): AIP Advances, Vol 11, Iss 1, Pp 015033-015033-4 (2021)

Abstract: The changes of magnetic properties upon heat treatment of a metastable supersaturated solid solution processed by severe plastic deformation are investigated by in situ AC-hysteresis measurements. Data are analyzed in the framework of dynamic loss theo...

Impact of interfaces on the radiation response and underlying defect recovery mechanisms in nanostructured Cu-Fe-Ag

Publication Type: Academic Journal

Source(s): Materials & Design, Vol 160, Iss , Pp 1148-1157 (2018)

Abstract: Newest developments in nuclear fission and fusion technology as well as planned long-distance space missions demand novel materials to withstand harsh, irradiative environments. Radiation-induced hardening and embrittlement are a concern that can lead ...

Magnetic dilution by severe plastic deformation

Publication Type: Academic Journal

Source(s): AIP Advances, Vol 10, Iss 1, Pp 015210-015210-5 (2020)

Abstract: Mixtures of Fe and Cu powders are cold-compacted and subsequently deformed with severe plastic deformation by high-pressure torsion, leading to bulk samples. The dilution of Fe in the Cu matrix is investigated with SQUID-magnetometry, whereas the magne...
