Notes:
Hydrostatic extrusion can be viewed as one of the methods of Severe PlasticDeformation, SPD, for the fabrication of ultra-fine grained alloys which causes a significantincrease in the mechanical properties such as tensile strength and hardness. In the present study themicrostructure of 6082 aluminium alloy after hydrostatic extrusion was investigated.Hydroextrusion was performed in three steps with accumulated true strains of 1.34, 2.73 and 3.74respectively. Microstructural observations were carried out using SEM, TEM and light microscopy.Grain and inclusion sizes, shapes and distribution were investigated in the HE processed samples.The study has shown that the hydrostatic extrusion process results in a profound refinement of boththe grain size and the inclusions in 6082 aluminium alloy
