Researches to increase the autonomy of electric vehicles are underway either on the batteries technology or on the lightening of the vehicle parts. For the second approach, one way is to replace aluminium parts by magnesium parts without losing mechanical performance or corrosion resistance. The present work starts with a study of solidification of AZ91, involving differential thermal analysis to evidence the sequence of solidification reactions. A metallographic study of die cast alloy and of the D.T.A samples and electron probe microanalysis yield information on the elements distribution and on the solidified microstructure scale. Tensile and hardness tests performed on die cast samples give some insight on the distribution of strength and on the effect of macroscopic solidification defects. Together with a literature survey of performance / constitution and microstructure relationships for this class of alloy, this study serves as the starting point for an approach towards property improvements.
