Precipitation and Hardening in Magnesium Alloys
TL;DR: In this paper, a review of precipitation in most precipitation-hardenable magnesium alloys is reviewed, and its relationship with strengthening is examined, and it is demonstrated that the precipitation phenomena in these alloys, especially in the very early stage of the precipitation process, are still far from being well understood, and many fundamental issues remain unsolved even after some extensive and concerted efforts made in the past 12 years.

Twinning and the ductility of magnesium alloys: Part II. “Contraction” twins
TL;DR: In this paper, a series of tensile and compression tests results are reported for common wrought alloys: AZ31, ZK60 and ZM20, and these data are combined with EBSD analysis and simple flow stress models to argue the following: (i) contraction double twinning (which enables contraction along the c axis) can decrease the uniform elongation, and (ii) compression double twinening can also account for shear failure at low strains.
