摘要：
The paper deals with the influence of processing conditions on tensile properties, hardness and structure development of the aluminium alloy EN AW 2014, depending on various processing conditions (as-rolling, quenching, severe plastic deformation - SPD by equal channel angular pressing - ECAP and ageing). The evaluated tensile properties showed that ECAP has the highest effect on the material properties of aluminium alloy EN AW 2014. Severe plastic deformation by means of ECAP caused rapid increase of strength and only partial decrease of ductility was achieved. Strengthening of material is caused by grains refinement and strain hardening of solid solution. Based on the results above, the tensile properties, hardness and structure development of the EN AW 2014 alloy are discussed.
