Abstract

L'invention concerne des alliages à base de magnésium et plus particulièrement la composition d'alliages à base de magnésium et des procédés de leur fabrication qui sont largement utilisés en industrie automobile. L'invention vise à fabriquer un alliage possédant une granularité plus faible, ce qui permet d'améliorer les propriétés mécaniques de l'alliage. Elle permet de fabriquer un alliage ayant des propriétés mécaniques adaptées au moulage par pression. On utilise un alliage à base de magnésium contenant de l'aluminium, du zinc, du manganèse, du silicium et du calcium. La nouveauté consiste en ce que cet alliage comprend les composants suivants, en % en masse: aluminium 8,5-9,5; zinc 0,45-0,90; manganèse 0,1-0,40; silicium 0,21-0,50; calcium 0,05-0,10; le reste étant constitué de magnésium.
