Abstract

Comprehensive attention has been focused globally on producing lightweight Mg-based alloys for automotive applications, which can perform well at operating temperatures (200–300ºC). This study examines the age-hardening behavior of Mg–10Sn alloys for enhanced performance. Room-temperature tensile investigations show that artificially aging for 100 h at 200ºC maximizes both tensile strength and ductility. Thermal aging at 200ºC for 100 h significantly increases work hardening capabilities, evidenced by a high strain-hardening rate ( = 2.10) and a hardening exponent (n) of 0.4167. This elevates the necking stress to 122 MPa and boosts load-bearing capacity (H_C) from H_C = 0.63 to 0.75 in Mg–10Sn alloy. The observed trend in strain-hardening behavior suggests a two-stage work-hardening response, driven by the precipitation of Mg₂Sn intermetallic at α-Mg grain boundaries, which significantly enhances the strength.
