These [metals] have the source arrangement of the two external shells of electrons in their atoms, and resemble one another very closely in chemical and physical properties, being thus most difficult to separate from each other. It is to this, rather than their actual rarity in nature, that they are so described. 3, record 1, English, - rare%20earth%20metals

On désigne sous le nom de «métaux des terres rares» quinze éléments consécutifs de la classification, allant du numéro 57 au numéro 71. Ce sont le lanthane, le cérium, le praséodyme, le néodyme, le prométhéum, le somarium, l'europium, le gadolinium, le terbium, le dysprosium, l'holmium, l'erbium, le thulium, l'hytterbium et le lutétium. À ce groupe on adjoint fréquemment le scandium et l'yttrium, de propriétés très voisines. 2, record 1, French, - m%C3%A9taux%20des%20terres%20rares

Irradiation-induced swelling, also known as void swelling (VS), occurs in austenitic stainless steels and nickel-base alloys during neutron bombardment. Voids grow due to the migration and condensation of vacancies on the void nuclei (which can be gas bubbles) leading to an increase In material volume. This phenomenon is dependent on temperature, neutron flux, and neutron fluence. Swelling is typically a concern for fast reactors at temperatures above 350°C (662°F). 1, record 2, English, - irradiation%2Dinduced%20swelling

La section efficace d’absorption neutronique du dysprosium est relativement élevée dans le domaine des neutrons thermiques ce qui confère au titanate une efficacité comparable aux matériaux classiques [...] Sous irradiation, le matériau se dégrade peu. Le gonflement de la phase fluorine est faible [moins de] 0, 5 % en volume pour une fluence de 1022 neutrons par cm² en neutrons thermiques à 250-450 °C. Les phases orthorhombiques et hexagonales montrent un gonflement plus important, essentiellement dû aux changements de phases O[ vers] H[ vers] F, d’où l'intérêt de l'utilisation de la phase cubique stabilisée. Le matériau a été utilisé soit sous forme de poudres vibrocompactées, soit sous forme de pastilles frittées. Pour les poudres, le faible gonflement entraîne l'absence de déformation des gaines les contenant. Pour les pastilles, une fissuration apparaît dans les matériaux irradiés sous forte fluence du fait des contraintes dues aux dilatations différentielles induites par les gradients thermiques élevés([plus de] > 60 °C/mm). 1, record 2, French, - gonflement%20sous%20irradiation

Les magnétorestrictifs sont utilisés dans les sonars pour générer des ondes acoustiques en faisant osciller un barreau sous l’action d’un champ magnétique alternatif. On a construit aussi des moteurs linéaires capables de déplacer de très fortes charges à de très faibles vitesses, par exemple pour les positionner avec précision. A l’inverse, les magnétorestrictifs sont utilisés dans des capteurs : ils transforment alors un déplacement en un signal électrique. La robotique, l’instrumentation scientifique et médicale, ou bientôt, les «matériaux intelligents» font partie des domaines d’application des magnétorestrictifs. 1, record 4, French, - magn%C3%A9torestrictif
