Abstract[English]
The disclosure provides aluminum alloy compositions comprising a rare earth metal such as Ce, La, or mischmetal, Zn, and Mg suitable for high pressure die casting that can be heat treated to achieve increased strength compared to existing Al alloys cast by high pressure die casting (HPDC). The alloy also allows for elimination of solutionizing step in heat treatment of castings made by gravity die casting (GDC) or low pressure die casting (LPDC) to reduce greenhouse gas emissions as well as process cost and processing steps and time while obtaining higher hardness, tensile strength, and yield strength.[French]
La présente divulgation concerne des compositions d'alliage d'aluminium comprenant un métal de terres rares tel que Ce, La ou mischmétal, Zn et Mg appropriées pour une coulée sous pression à haute pression qui peuvent être traitées thermiquement pour obtenir une résistance accrue par rapport aux alliages d'Al existants coulés par coulée sous pression à haute pression (HPDC). L'alliage permet également l'élimination de l'étape de mise en solution dans le traitement thermique de pièces coulées réalisées par coulée sous pression (GDC) ou coulée sous pression à basse pression (LPDC) pour réduire les émissions de gaz à effet de serre ainsi que les étapes et le temps de traitement tout en obtenant une dureté, une résistance à la traction et une limite d'élasticité supérieures.
