Natural Ageing of Al–Fe(Zn,Mg) Alloy Castings for Structural Automotive Application

Abstract.Novel Al–Fe-based eutectic alloys with Zn and Mg as precipitation strengtheners were used in the manufacturing of test plates using high-vacuum high-pressure die casting to evaluate the feasibility of manufacturing structural automotive components with a higher strength to weight ratio than the present. Natural ageing at room temperature is a typical behaviour of this new alloy due to the continuous precipitation reactions of the Zn …
