Constrained groove pressing (CGP) is a severe plastic deformation technique which was successfully applied to aluminium alloys production. Its proved efficiency can be also employed for magnesium alloys. In this study AZ31 and ZE10 magnesium alloy sheets produced using twin-roll casting (TRC) were subjected to CGP. Evolution of the microstructure, texture and mechanical properties was studied using light optical and scanning electron microscopy as well as microhardness and tensile testing. Results show that the combination of TRC and CGP results in improvement of materials properties. The effect of the alloys composition on the mechanical behavior was also studied. Due to the presence of rare-earth elements it is possible to stint recrystallization in ZE10 alloy, thus, a finer grain structure is achieved. Crucial features of the brand new class of sheet structural alloys with high solid solution supersaturation imposed by TRC and ultra-fine grained structure after CGP are distinguished.
