| Research Abstract |
The purpose of this research work was to develop a novel heat treatable wrought magnesium based alloy, which exhibits excellent strength and room temperature formability. As a result of alloy search using cast alloys, a Mg-Sn-Zn-Al alloy was found to exhibit substantial precipitation hardening. The extrusion condition and heat treatment schedule (e.g., solution treatment and aging treatment) were optimized based on the detailed nano-/micro-structure characterization by SEM, TEM and 3D atom probe. The newly developed Mg-Sn-Zn-Al extruded alloy exhibited high yield strength of over 350 MPa along with the large elongation to failure up to 15 % after aging treatment.
