Purpose: The foundation of the resolved problem consists of verification of influence of temperature and also geometry of the ECAP tool on obtaining of required amount of deformation which substantially influences grain size. Research was realised with use of the alloy AlMn1Cu. Verification concerned influence of change or route of deformation on amount of deformation aimed at obtaining of required grain refinement. Design/methodology/approach: At the first stage of solution mathematical simulation was used for determination of conditions for obtaining the required amount of material deformation. Experimental part of the work was then made on the basis of results of the mathematical simulation. Findings: Route of deformation was changed by deflection of horizontal part of the ECAP channel by 10 and 20°. Obtained results were compared with conventional ECAP process without deflection of the channel. Increased efficiency of the ECAP process was confirmed unequivocally. Practical implications: Practical application of the obtained results at forming of the given alloy in the company AlInvest Bridlicna will bring economy of forming operations, as well as operations of heat treatment of that alloy. Originality/value: The obtained results will be verified by designing of new device enabling forming of strip of sheet. This type of alloy is used for production of strip of sheet by technology of successive rolling to the required thickness with required mechanical properties with preservation of the required formability.
