Abstract: Age-hardening, or precipitation hardening, is a critical heat treatment process that enhances the mechanical properties of aluminum alloys by forming finely dispersed precipitates within the matrix. This review comprehensively examines the mechanisms, kinetics, and influencing factors of age-hardening in aluminium alloys, with a focus on the role of alloying elements, aging temperatures, and time. Recent advancements in characterization techniques, computational modelling, and novel aging processes are also discussed. The review consolidates findings from over 50 studies to provide a detailed understanding of precipitation sequences, hardening effects, and industrial applications.
