Abstract
Mg-5.4Sn-4.2Zn-2.1Al-0.2Mn (TZAM5420) and Mg-5.4Sn-4.2Zn-2.1Al-0.2Mn-0.1Na (TZAM5420-0.1Na) alloys were extruded at various ram speeds, and the effect of the ram speed and T6 treatment on the strength was investigated. Particularly, the TZAM5420-0.1Na alloy extruded at 5 mm/s exhibited a yield strength of 334 MPa after the T6 treatment, which is more than 170 MPa higher than that of the as-extruded alloy. The high strength of the T6 aged TZAM5420-0.1Na alloy is attributed to the uniform dispersion of the fine precipitates and suppressed grain growth during the solution treatment.
