Typical Zirconium Alloys Microstructures in Nuclear ComponentsTypische Mikrostrukturen von Zirconiumlegierungen in Komponenten kerntechnischer Anlagen
(Carl Hanser Verlag, 2014-09)
The different microstructures typically found in nuclear components made of zirconium alloys are discussed in this paper. These include material in a variety of thermo-mechanical conditions, e.g., cold rolled, stress ...
Diagrama de fases experimental Fe-Sn-Zr. Nuevos resultados del corte isotérmico de 800°C
(Universidade Federal do Rio de Janeiro, 2018-02)
Las aleaciones de base Zr son de extendida aplicación en el campo de la tecnología nuclear. El Zr aleado con Sn y Fe es la base principal de las aleaciones tipo Zircaloy, aún hoy muy utilizadas como elementos estructurales ...
Characterization of stabilized ZrO2 thin films obtained by sol-gel method
(Elsevier Science, 2021-12)
In this work, the characterization of ZrO2 thin films synthesized by the sol-gel method, using two different routes, is presented. Thin films were deposited by dip-coating on glass and Zircaloy-4 (Zry-4) substrates, and ...
Monte Carlo simulation of neutron scattering by a textured polycrystal
(Wiley Blackwell Publishing, Inc, 2020-04)
A method of simulating the neutron scattering by a textured polycrystal is presented. It is based on an expansion of the scattering cross sections in terms of the spherical harmonics of the incident and scattering directions, ...
Characterization of crystallographic texture of Zirconium alloy components by neutron diffraction
(Elsevier Science, 2018-11)
The reproducibility of the determination of crystallographic texture of Zr-based components by neutron diffraction has been studied through a small round-robin exercise, with the participation of texture and residual stress ...
Quantification of dislocations densities in zirconium hydride by X-ray line profile analysis
(Pergamon-Elsevier Science Ltd, 2016-09-17)
Zirconium-based components in nuclear power plants are embrittled by precipitates of δ zirconium hydride, which involves a martensitic-type transformation of the hexagonal α-Zr lattice into the face-centered cubic Zr ...
Determination of very low concentrations of hydrogen in zirconium alloys by neutron imaging
(Elsevier Science, 2018-05)
Zr-based alloys are used in nuclear power plants because of a unique combination of very low neutron absorption and excellent mechanical properties and corrosion resistance at operating conditions. However, Hydrogen (H) ...
