Purpose: Magnesium alloys are the very progressive materials whereon is due to improve their end-use properties, which. Especially, wrought Mg alloys attract attention since they have more advantageous mechanical properties than cast Mg alloys. Design/methodology/approach: The presented article shows some specific physical-metallurgical characteristics of magnesium alloys of the AZ91 kind after hot forming. Special attention has been focused on the analysis of mutual relations existing between the deformation conditions, microstructural parameters, and the achieved mechanical properties. Findings: The discussed topic includes namely the monitoring of the structures in the initial cast state and after the heat treatment of the T4 kind and the influence of rolling in hot state at different temperatures on this structure. The results of torsion tests of AZ91, AZ61 and AZ31 were added. Research limitations/implications: The results of this paper evinces that a combination of ECAP technology with conventional rolling is very effective tool for improve a final properties of magnesium alloys in practical use. Practical implications: It would be appropriate a extrusions processes for increasing of mechanical properties on their treatment by plastic deformations in a rolling mills. Originality/value: It is explained a big consequence of the ECAP integration between classical forming techniques.
