Análisis de la permeación de tritio en los canales de metal líquido de las envolturas regeneradoras de un reactor de fusión en presencia de burbujas de helio
(2012)
Text en actes de congrés
Accés obertEn el interior de los canales de metal l quido de las envolturas regeneradoras de un reactor de fusi on, la posibilidad de existencia de burbujas de helio nucleado no es remota. El helio se forma junto al tritio en ... -
Fragility and glass-forming ability of the Ca-Mg-Cu system
(Elsevier, 2007-05-31)
Article
Accés obertElastic moduli of the glass and fragility of the corresponding supercooled liquid were found to be correlated in recently published results. In the present work, compositions within the Ca–Mg–Cu system are used to study ... -

Installation expérimentale de transferts de polluants d’un sel fondu vers un métal liquide de confinement par procédé électromagnétique – amélioration de l’installation et tests
(Universitat Politècnica de Catalunya / Institut National Polytechnique de Grenoble, 2009)
Projecte/Treball Final de Carrera
Accés restringit per decisió de l'autorIn most of the extracion or de-pollution relative to metallurgy, a mass transfer occurs through a liquid/liguid interface. The control of motion in the neighborhood and of the interface isa a prominent key to promote the ... -
Intrinsic correlation between the fraction of liquidlike zones and the beta relaxation in high-entropy metallic glasses
(American Institute of Physics (AIP), 2022-10-21)
Article
Accés obertLacking the structural information of crystalline solids, the origin of the relaxation dynamics of metallic glasses is unclear. Here, we report the evolution of stress relaxation of high-entropy metallic glasses with ... -
Nucleation of helium in pure liquid lithium
(American Institute of Physics (AIP), 2023-07-14)
Article
Accés obertTritium self-sufficiency in fusion nuclear reactors will be based on the neutron capture by lithium in the so-called breeding blankets of the reactor, a nuclear reaction that will produce helium along with tritium. The low ... -
Numeric implementation of a nucleation, growth and transport model for helium bubbles in lead–lithium HCLL breeding blanket channels: Theory and code development
(2011)
Article
Accés restringit per política de l'editorialLarge helium (He) production rates in liquid metal breeding blankets of a DT fusion reactor might have a significant influence in the system design. Low He solubility together with high local concentrations may create the ... -
On the determination of diffusion coefficients in two-component alloys and doped semiconductors: several implications concerning the International Space Station
(2015-07-01)
Article
Accés obertThe accurate determination of mass diffusion coefficients is a technologically relevant problem that has implications on the modelling and control of material processes such as crystal growth and casting. It is also important ... -
Parametrization of embedded-atom method potential for liquid lithium and lead-lithium eutectic alloy
(Elsevier, 2023-09)
Article
Accés obertLiquid lead-lithium eutectic remains as a promising candidate for various breeding-blanket designs in future nuclear-fusion technologies. The lack of a generalized theory of interatomic forces in the liquid state is reflected ... -

Comunicació de congrés
Accés restringit per política de l'editorialThe Institute for Plasma Research (IPR), India, is currently involved in the design and development of its Test Blanket Module (TBM) for testing in ITER (International Thermo nuclear Experimental Reactor). The Indian TBM ... -
Structural evolution of metallic glasses during annealing through in-situ Synchrotron X-ray diffract
(2008-05)
Article
Accés obertIn this work we study the structural evolution of Al and Fe based metallic glass compositions. The samples were obtained as ribbons by melt-spinning, their glass stability and crystallization were analyzed by calorimetry ... -
Theoretical approach to Poisson ratio behavior during structural changes in metallic glasses
(Americal Physical Society, 2006-03)
Article
Accés obertRecently, various studies dealing with the relationship between the elastic constants and various of the macroscopic properties of metallic glasses have been published. Particularly, the correlations between the Poisson’s ...
