ECAP methods application on selected non-ferrous metals and alloys

Purpose: Paper presents results of investigations mechanical properties and microstructure samples selected nonferrous metals after ECAP. These properties and microstructure are influenced by technological factors during application ECAP method. Design/methodology/approach: The sample bars were plastically deformed during the ECAP process. The methods of the light microscopy and the hardness test for evaluation of mechanical properties and microstructure were used. Findings: Measurement of micro-hardness shows an increase value after application higher number of passes in agreement with ultra high fine grain occurrence. The method determines the dependencies of force on the route during the ECAP process. Research limitations/implications: Achieved hardness and microstructure characteristics will be determined by new research. Practical implications: The results may be utilized for a relation between structure and properties of the investigated materials in future process of manufacturing. Originality/value: These results contribute to complex evaluation of properties new nonferrous metals after application ECAP method. The results of this paper are determined for research workers deal by the process severe plastic deformation.
