Abstract

The main objective of severe plastic deformation (SPD) methods is to obtain material with ultra-fine grained microstructure. Large deformations introduced during SPD processes result in extensive refinement of initial coarse microstructure which has significant influence on overall mechanical properties of such materials. In this work 413.0 aluminum alloy has been subjected to extrusion and equal channel angular pressing (ECAP). Metal chips obtained from machining process have been pre-compacted into a form of cylindrical billets and then extruded at elevated temperature into longitudinal square profile with cross section of 10 x 10 mm. In the second part of the experiment samples cut from this extrudate has been subjected to ECAP deformation through the 90° die. Mechanical properties were determined by uniaxial tensile tests and microhardness measurements has been performed. Structural observations did not reveal any significant changes in particles size after ECAP but enhancement of mechanical properties has been noticed and attributed to the work hardening of the aluminum matrix.
