Anisotropic mechanical properties and microstructural origins of a high strength Al–Zn–Mg–Cu alloy under various loading conditions

Key Points

• Anisotropic mechanical properties were observed, indicating the unique responsiveness of the alloy under different loading conditions.
• A significant tensile strength of 650 MPa was recorded when tested in the rolling direction.
• Assessment using microstructural analysis techniques revealed the role of grain orientation and phase distribution.
• This highlights the need for careful consideration of processing methods to optimize mechanical performance.
