Fabrication of simulated plate fuel elements: Defining role of stress relief annealing
Journal of Nuclear Materials, 2014Abstract 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, 1983The 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

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, 2014A 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.

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.

Effects of stress-relief pre-annealing on deuterium trapping and diffusion in tungsten
Fusion Engineering and Design, 2017Abstract 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

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 ...

Effect of stress-relief annealing on the inverse swift effect in steel and iron
Scripta Metallurgica et Materialia, 1995The Swift effect (1) refers to the length changes that take place in metal bars and hollow tubes during torsional deformation to large strains. The inverse Swift effect reverse to the twisting that accompanies axial elongation when pretwisted samples are loaded in free extension. In this work, free end tensile tests were performed on plain carbon steel
