Abstract

Cette invention se rapporte au domaine du frittage, et peut être utilisée dans la production de matériaux utilisés dans le bâtiment, en aviation, dans la construction automobile et dans la construction d'ascenseurs. Les poudres d'alliages d'aluminium sont mélangées à des porophores dont la température de désagrégation est supérieure à la température solidus-liquidus de la poudre d'alliage d'aluminium. On verse ensuite le mélange obtenu dans un récipient en alliage d'aluminium, on effectue un compactage préalable, puis on chauffe le récipient contenant le mélange compacté jusqu'à une température de 10 à 20° C inférieure à la température de solidus de la composante la plus facilement fusible de l'alliage d'aluminium. On effectue ensuite un pressage à chaud, puis on réchauffe l'ébauche pressée jusqu'à une température de 10 à 20° C inférieure à la température de solidus de la composante la plus facilement fusible de l'alliage d'aluminium. On soumet ensuite l'ébauche à une déformation à chaud, on la refroidit, puis on effectue un traitement thermique à haute température dans le moule en soumettant l'ébauche à un chauffage uniforme et omnidirectionnel jusqu'à une température de 40 à 70° C supérieure à la température de transition de phase solide-liquide, et on refroidit enfin ladite ébauche. Dans un second mode de réalisation, la déformation à chaud de l'ébauche pressée se fait par laminage de manière à lui donner la forme d'une feuille, tandis qu'avant le traitement thermique à haute température, ladite ébauche est chauffée à une température de 350 à 450° C et maintenue à cette température pendant 90 à 120 minutes avant d'être mise sous forme de produit fini. Dans un troisième mode de réalisation, l'ébauche pressée obtenue avant le traitement thermique à haute température se présente sous forme de barre. Cette invention permet d'augmenter la production et d'élargir l'éventail des produits semi-finis et des articles finis poreux et acceptables.
