Magnetostrictive loss reduction through stress relief annealing in an FeNi-based metal amorphous nanocomposite

Journal of Materials Research, 2021
FeNi-based metal amorphous nanocomposite alloys are emerging soft magnetic materials with promise for high-speed motor applications. Here we demonstrate a technique to optimize magnetic properties in toroidal cores wound from strain annealed (Fe70Ni30)80Nb4Si2B14 amorphous metal ribbon (AMR).

Stress relief of tetrahedral amorphous carbon films by post-deposition thermal annealing

Surface and Coatings Technology, 1999
The stress relief of tetrahedral amorphous carbon (ta-C ) films by post-deposition thermal annealing was investigated. The films were subjected to rapid thermal annealing (RTA) for 2 min and conventional furnace annealing (CFA) for 30 min. In both cases, the films were annealed in vacuum with argon (4◊10’2 Torr) at successive higher temperatures ...

Fabrication of simulated plate fuel elements: Defining role of stress relief annealing

Journal of Nuclear Materials, 2014
Abstract This study involved fabrication of simulated plate fuel elements. Uranium silicide of actual fuel elements was replaced with yttria. The fabrication stages were otherwise identical. The final cold rolled and/or straightened plates, without stress relief, showed an inverse relationship between bond strength and out of plane residual shear ...

Stress relief of basal orientation zinc oxide thin films by isothermal annealing

Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 1983
The effect of isothermal annealing on residual strain in the lattice of as-deposited basal crystallographic orientation zinc oxide was studied. Films were prepared by rf diode sputter deposition from a zinc oxide target and annealed in air for 5 to 1995 min at 300 or 500 °C. The change in crystallography as a result of annealing was determined by x-ray

Stress relief by annealing under external stress in Fe-based metallic glasses

Journal of Applied Physics, 2018
The effects of stress relief on the magnetic characteristics of Fe-based metallic glass (MG) ribbons are investigated under external stress through various annealing treatments. We found that long-time annealing treatments benefit for making softer magnetic MGs under applied bending stress.

Nucleation rate reduction through stress relief of thermally annealed hydrogenated amorphous silicon films

Journal of Applied Physics, 2013
The effect of film stress on crystallite nucleation is investigated in 0.11  μm thick, thermally annealed hydrogenated amorphous silicon films. Using a recently developed optical method, the crystallite density is measured as the films are isochronally annealed at 600 °C, which enables the determination of the crystallite nucleation rate.

The Research of Non-Oriented Electrical Steel Processed by Stress Relief Annealing Experiments

Advanced Materials Research, 2014
A high grade non-oriented electrical steel final annealing product was processed by stress relief annealing experiments under pure hydrogen atmosphere using different process parameters. The samples were compared in the aspects of magnetic properties and anisotropy, then analyzed the phenomena concerned with grain size, texture and precipitates aspects.

Effects of stress-relief pre-annealing on deuterium trapping and diffusion in tungsten

Fusion Engineering and Design, 2017
Abstract Positron annihilation Doppler broadening spectroscopy (PA-DBS) with slow positrons was utilized to characterize the change of vacancy-type defects induced by a stress-relief annealing (1273 K for 1 h in vacuum) as pre-annealing can remove not only residual stresses but also most intrinsic defects of the material. Deuterium behavior after low

Fracture properties of hydrided Zircaloy-4 cladding in recrystallization and stress-relief anneal conditions

Journal of Nuclear Materials, 2012
Abstract In this work, the stress-relieved (SRA) and recrystallized (RXA) Zircaloy-4 cladding specimens were hydrogen-charged to the target concentration of 300 wppm and then manufactured into X-specimens for fracture toughness test. The hydrogen embrittlement susceptibility of Zircaloy-4 cladding specimens in both SRA and RXA conditions were ...

Stress-Relief Annealed High-Strength Sheet Steel - Properties and Applications

SAE Technical Paper Series, 1980
<div class="htmlview paragraph">The high-strength properties of stress-relief annealed (SRA) steel are developed by processing rather than by alloying. The mechanical properties and their reproducibility as well as the properties commonly used to predict formability are described.
