Abstract

La présente invention concerne un matériau en alliage et un procédé de production de barres fabriquées à partir de celui-ci. La présente invention concerne un matériau en alliage comprenant les composants suivants en poids : 0,8 à 1,2 % de Si, 0 à 0,5 % de Fe, 0,15 à 0,6 % de Cu, 0,2 à 0,8 % de Mn, 0,6 à 0,1 % de Mg, 0 à 0,1 % de Cr, 0 à 0,25 % de Zn et 0 à 0,1 % de Ti, le reste étant AL, la teneur en Si étant de 1,11 %, et la teneur en Mn étant de 0,69 %. L'invention concerne en outre un procédé de production d'un matériau en alliage comprenant les étapes suivantes consistant à : (1) Peser les matières premières de chaque composant en pourcentage en masse ; (2) placer les matières premières dans un four de fusion et les faire fondre en un liquide d'alliage, la température du liquide d'alliage pouvant atteindre 705 à 750 °C, maintenir ladite température pendant 45 à 60 min ; (3) réduire la température du liquide d'alliage à 520-580 °C, ajouter un agent de raffinage, augmenter la température à 670-710 °C, et réaliser une inspection des composants ; (4) laisser reposer le liquide d'alliage et refroidir celui-ci à 650-660 °C, effectuer un remplissage de moule, et refroidir le liquide d'alliage en barres. Le matériau en alliage fourni par la présente invention est caractérisé par une résistance à la traction élevée et une grande limite d'élasticité.
