Microstructural and Mechanical Characterization after Thermomechanical Treatments in 6063 Aluminum Alloy

The aim of this work is the mechanical and microstructural characterization by optical and electron microscopy as well as microhardness of Al 6063 alloy after mechanical and thermal treatment. Al-Mg based alloys have special attention due to the lightness of the material and certain mechanical properties and recyclability. Such alloys produce good me-chanical properties in moderate mechanical efforts (up to 700 MPa) and good resistance to the corrosion. Cold rolling steps (30%, 60 % and 90 % in area reduction) in Al 6063 alloy were employed for the recrystallization studies, followe
