Al3Zn
metal· JVASP-79127· Al3Zn
Al₃Zn is an intermetallic compound consisting of aluminum and zinc in a 3:1 stoichiometric ratio, representing a distinct phase that forms within the Al-Zn binary system. This material is primarily encountered as a constituent phase in aluminum-zinc alloys rather than as a standalone engineering material, where it contributes to precipitation hardening and age-hardening mechanisms in commercial alloys like 7xxx-series aluminum. Al₃Zn's significance lies in its role in controlling mechanical properties through microstructural engineering; understanding its formation and dissolution kinetics is critical for heat-treatment optimization of high-strength aerospace and automotive components.
