Purpose: of this paper is to extend a complex evaluation of aluminium alloy, which requires very often knowledge of behaviour of deformation at the ECAP process and achieved strengthening, intensity of deformation and very fine structure. These factors have influence on the mechanical properties and formability. Presented knowledge expresses very important information for exploitation of this alloy. Design/methodology/approach: The methods determining the dependencies of force on the route during the ECAP process were used. Achieved values were directly plotted on PC. Findings: Conclusions of this work consisted in determination of structure and mechanical properties of this alloy. Research limitations/implications: Achieved hardness and microstructure of this alloy will be determined by new research. Practical implications: The results may be utilized for determination of a relation between structure and properties of the investigated alloy in the process of manufacturing. Originality/value: These results contribute to complex evaluation of properties of the AlMn1Cu alloy, namely in the light of achievement of very fine - grained structures and corresponding mechanical and forming properties. The results of this paper are determined for research workers – in order to increase efficiency of the process of severe plastic deformation.
