Magnesium: Properties — applications — potential
B.L Mordike,T Ebert +1 more
TL;DR: Magnesium is the lightest of all metals used as the basis for constructional alloys and it is this property which entices automobile manufacturers to replace denser materials, not only steels, cast irons and copper base alloys but even aluminium alloys by magnesium based alloys as discussed by the authors.

The interaction of twins and precipitates in a Mg-7.7 at.% Al alloy
TL;DR: In this paper, the nature of the interaction between the twins and the second phase was found to be dependent on the relative thickness of the twin and the precipitate, and a model based on basal plane slip in the twin was invoked to explain these features.
