Formation and Dispersion of Precipitates during Hot Deformation in Al–1%Mn Alloys

In this study, precipitation behavior in hot workings on Al–1%Mn alloy was investigated. It has been identified specimens used study show thermally stabilized substructures after plain strain compression (PSC) test as a working. PSC tests were carried out between 300°C and 500°C. By using small angle x-ray scattering (SAXS) method, dispersion state of precipitations formed estimated. considered minute less than 10 nm diameter worked areas. These increased with increasing temperature. invariant area heated at 400°C, not identified. HAADF-STEM, these confirmed, it cleared due to EDS analysis the consist four elements such aluminum, manganese, iron silicon.
