Superior thermal stability in a high-strength Al–Zn–Mg–Cu–Si alloy via tailored precipitation sequence

Superior thermal stability in a high-strength Al–Zn–Mg–Cu–Si alloy via tailored precipitation sequence

Here, a novel Al–Zn–Mg–Cu–Si alloy is developed, combining a high yield strength of ∼420 MPa with excellent thermal stability. This exceptional performance is achieved through a tailored precipitation sequence enabled by a multi-step aging strategy. The first aging step at 80 °C plays a crucial role...
