نویسندگان
چکیده
By combining differential scanning calorimetry analysis and high-resolution transmission electron microscopy observations, the precipitation map for Al–Cu–Mg alloy (AA2024-T3) is obtained a wide temperature range from 85 to 250 °C ageing durations 1 10,000 h. For first time, appearance of equilibrium S–Al2CuMg phase observed at 1000 h ageing. Hardness values superposed with reveal that maximum hardness all studied temperatures located frontier between S-phase + Guinier-Preston-Bagaryatski (GPB) zones regions.

Longitudinal Residual Stress Analysis in AA2024-T3 Friction Stir Welding
Friction Stir Welding (FSW) is an innovative solid-state joining process, which is gaining a great deal of attention in several applicative sectors. The opportune definition of process parameters, i.e. minimizing residual stresses, is crucial to improve joint reliability in terms of static and dynamic performance. Longitudinal residual stresses, induced by FSW in AA2024-T3 butt joints, have bee...
متن کاملThe corrosion protection of AA2024-T3 aluminium alloy by leaching of lithium-containing salts from organic coatings.
Lithium carbonate and lithium oxalate were incorporated as leachable corrosion inhibitors in model organic coatings for the protection of AA2024-T3. The coated samples were artificially damaged with a scribe. It was found that the lithium-salts are able to leach from the organic coating and form a protective layer in the scribe on AA2024-T3 under neutral salt spray conditions. The present paper...

متن کاملInhibition effect of cerium in hybrid sol–gel films on aluminium alloy AA2024†
Aluminium alloys such as AA2024 are susceptible to severe corrosion attack in aggressive solutions (e.g. chlorides). Conversion coatings, like chromate, or rare earth conversion coatings are usually applied in order to improve corrosion behaviour of aluminium alloys. Methacrylate-based hybrid films deposited with sol–gel technique might be an alternative to conversion coatings. Barrier properti...
