Interplay of dynamic strain aging and dynamic precipitation in the Portevin–Le Châtelier effect in an Al-Mg-Zn-based crossover aluminum alloy

Key Points

• The Portevin–Le Châtelier effect significantly alters mechanical behavior under dynamic strain aging conditions.
• Dynamic strain aging leads to increased dislocation density, impacting the yield strength of the aluminum alloy.
• Analysis of material properties indicates a unique interplay between dynamic precipitation and strain aging.
• Understanding these mechanisms supports the development of advanced metallic components for various applications.
