Modelling of plastic deformation in magnesium [PDF]
In the present contribution, a viscoplastic rate-dependent constitutive model based on Schmid’s law has been used to designate the activity level of pure magnesium deformation systems. A crystal plasticity model in the framework of finite elements was used to investigate the deformation systems on the scale of single- and polycrystals.

Effect of a plastic deformation on the Guinier-Preston zones growth in Al-5at%Ag alloy
The formation of the Guinier-Preston zones in aluminium alloys is closely linked with the excess vacancies. A plastic deformation exerts an influence on the Guinier-Preston zones precipitation.
