On the possibility of producing a nanocrystalline structure in magnesium and magnesium alloys

Abstract The mechanical properties and structural evolution of pure magnesium and Mg6%Zn0,65%Zr alloy during cold plastic deformation has been analysed. It has been shown that dynamic recrystallization (DRX) occurs in both the materials. Specific features of the recrystallized structure are considered. The influence of chemical and phase composition of the material on the formed structure is analysed as well. An attempt is made to determine the conditions necessary for obtaining a nanoscale grain size in the material.
