Abstract

L'invention concerne un procédé de production de pistons pour produire un piston de moteur à combustion interne. Le procédé comporte les étapes consistant à : forger une billette à partir d'une billette initiale en alliage d'aluminium, qui contient du silicium, des particules intermétalliques et des particules de trempe injectées, le forgeage étant mis en oeuvre dans des conditions de super-plasticité et/ou de déformation à chaud; et traiter à chaud la billette forgée. Le forgeage comporte une opération de forgeage à une température se situant entre environ 0,8 T¿fusion? et environ 0,98 T¿fusion?. Le forgeage comporte également une opération de forgeage à une vitesse de déformation se situant entre environ 5x10?-2¿ s?-1¿ et environ 5x10?-5¿ s?-1¿. Le piston est formé selon une configuration qui permet de connecter d'autres éléments au piston. La billette initiale comporte au moins un élément du groupe comprenant du silicium gros grain, des particules intermétalliques et des particules de trempe injectées présentant une forme globale lamellaire, ou du groupe comprenant des particules de silicium à grain fin, des particules intermétalliques et des particules de trempe injectées présentant une forme sphérique. La proportion en volume des particules de silicium, intermétalliques et de trempe injectées se situe entre environ 25 % et environ 60 %, et la taille moyenne des grains des particules de silicium, intermétalliques et de trempe injectées est inférieure à environ 15 µm?2¿.
