Title (EN) EXTRUDED PRODUCT MADE FROM AL-CU-MG ALLOY WITH IMPROVED COMPROMISE BETWEEN MECHANICAL RESISTANCE AND TOUGHNESS
(FR) PRODUIT EXTRUDE EN ALLIAGE AL-CU-MG A COMPROMIS AMELIORE ENTRE RESISTANCE MECANIQUE ET TENACITE
Abstract:
(EN) The invention relates to an extruded product made from an alloy of composition (% by weight): Cu: 5.05-5.35; Mg: 0.20-0.40; Mn: 0.20-0.40; Zr: 0.08-0.1; Ti: 0.01-0.15; Zn: 0-0.15; Si < 0.10; Fe < 0.15 and other elements < 0.05 each and < 0.15 in total, the remainder being Al, treated by dissolving, at a temperature between 525 and 540 °C, quenching, controlled traction during quenching until a permanent deformation of at least 1.5% is achieved, and returning to a temperature of between 160 and 190 °C. The products according to the invention are particularly well suited to use as pistons in an internal combustion engine of a vehicle and in particular of a racing car.
(FR) L'invention concerne un produit extrudé en alliage de composition (% en poids) : Cu : 5,05 –5,35 Mg : 0,20 –0,40 Mn : 0,20 –0,40 Zr : 0,08 –0,1 Ti : 0,01 –0,15 Zn : 0 -0,15 Si< 0,10 Fe < 0,15 autres éléments < 0,05 chacun et < 0,15 au total, reste Al, traité par mise en solution,à une température comprise entre 525 et 540 °C, trempe, traction contrôlée trempé jusqu'à une déformation permanente d'au moins 1,5%,et revenu à une température comprise entre 160 et 190 °C. Les produits selon l'invention se prêtent particulièrement bien à l'utilisation comme piston dans un moteur à combustion interne de véhicule et en particulier de voiture de course.
