In a nuclear plant of Westinghouse design the reactor coolant system components may be forged or cast stainless steel and varies from plant to plant. The reactor coolant pump casings are always cast. Both forged and cast product forms exhibit exceptionally high toughness in the as-build condition; however, the cast material is susceptible to thermal aging. Thermal aging causes significant reduction in fracture toughness, while the tensile strength and yield stress of the materials most often increase. 1, record 1, English, - thermal%20aging

La dénomination de «vieillissement thermique» recouvre toute une série de mécanismes basés sur la diffusion des éléments chimiques et permettant aux «systèmes» métallurgiques de revenir à un état d’équilibre thermodynamique plus stable, sous l'effet de la température de fonctionnement(entre 290 et 350 °C dans le cœur des REP [réacteur à eau sous pression]). Ce retour à l'équilibre se traduit par une évolution microstructurale et par une évolution des propriétés des matériaux. Les principaux mécanismes de vieillissement thermique susceptibles d’apparaître sont la précipitation, la mise en ordre, le vieillissement dynamique et la ségrégation de certaines espèces chimiques. Tous ces mécanismes conduisent plus ou moins à une fragilisation du matériau(avec ou sans durcissement). 3, record 1, French, - vieillissement%20thermique

Scleroderma is a chronic autoimmune disease ... The term scleroderma means "hard skin", which describes thickening of the skin from increased deposition of collagen. There are two types of scleroderma. Localized scleroderma affects the skin and musculoskeletal system. Systemic sclerosis causes internal organ damage including scarring and blood vessel damage in the skin, lungs, heart, and kidneys. 5, record 2, English, - scleroderma

[Scleroderma] was formerly known as "skin-bound" or "hide-bound" disease. Both of these terms accurately describe the ultimate effects of thickening of the skin due to swelling and thickening of the underlying connective tissue... The actual cause is unknown, but vascular, endocrine and autoimmune factors have been suspected. 3, record 2, English, - scleroderma

La sclérodermie est une maladie rare [...] qui affecte essentiellement la peau, mais aussi, dans sa forme généralisée ou systémique, les organes interne(rein, cœur, poumons, etc...) [...] Le terme «sclérodermie» décrit assez bien en lui seul le principal signe ou symptôme de la maladie. Du grec «skleros» : dur et «derma» : peau, sclérodermie signifie donc «durcissement de la peau». 1, record 2, French, - scl%C3%A9rodermie

L'implantation ionique est utilisée en électronique pour doper les semi-conducteurs. Dans la fabrication des tranches de silicium destinées à recevoir des microcircuits, on implante des atomes d’oxygène pour former une couche isolante au cœur de la matière. En métallurgie, l'implantation ionique d’atomes d’azote est utilisée pour le durcissement superficiel de métaux comme le titane. 3, record 4, French, - implantation%20ionique
