Aluminum 5052 alloy have high strength, light weight and excellent corrosion resistance properties for high speed, fuel efficient application in automobile industries. It also has low neutron capture cross section, fracture toughness and excellent mechanical properties for longer duration usage, which makes it suitable for new generation nuclear batteries and research reactors. Aluminum 5052 alloy has more than 2.5% of Mg. At higher temperature (> 65°C) the magnesium in the alloy mitigates to the grain boundary and combines with aluminum to form β-particle of Al3Mg2 at the grain boundaries. This process is known as sensitization and it leads to intergranular corrosion, exfoliation and stress corrosion cracking of the alloy under stress and corrosive environment. The Aluminum 5052 alloy properties can be improved by reverse sensitizing with stabilized treatment and restoring corrosion resisting by Pulsed electron beam from ETIGO-III. The experimental results of sensitized samples of different thickness with pulsed electron beam on ETIGO-III pulsed power generator and its analysis will be presented in the conference.
