Due to their high specific strength and low density, 7075 Al alloys are widely used in aerospace applications. However, Al alloys are prone to corrosion and deterioration, and the service life depends on their corrosion resistance. To investigate the corrosion and strengthening mechanisms of the 707...
Light-weight, high-strength, aluminum (Al) alloys have widespread industrial applications. However, most commercially available high-strength Al alloys, like AA 7075, are not suitable for additive manufacturing due to their high susceptibility to solidif
Aluminum alloys of the 7075 type (Al-Zn-Mg-Cu) are widely used in airframe structures; they provide very high strength and stiffness, but are prone to stress corrosion cracking (SCC), particularly when aged to the near-peak-strength T6 condition. Their resistance to SCC can be increased by...
