Abstract Scope |
Heat treatable wrought magnesium alloy is promising as a strong and formable alloy sheet because Mg-Al-Zn-Ca-Mn and Mg-Zn-Ca-Zr alloys demonstrated comparable room temperature formability and strength with 6XXX series aluminum. This presentation will discuss strategies to achieve excellent room temperature formability and high strength in magnesium alloy sheets.
The addition of Zn is beneficial in achieving good room temperature formability in the Mg-Ca-Al dilute alloy by texture weakening because the Zn addition facilitates the nucleation of weakly textured grains along twin boundaries during the solution treatment. However, the Zn content should be optimized to achieve satisfactory bake-hardenability, which is a unique feature that occurs in the dilute magnesium alloys strengthened by the precipitation of Guinier Preston (G.P.) zones. These bake-hardenable alloys exhibit high thermal conductivity. Therefore, the bake-hardenable magnesium alloy sheet is expected to broaden the application of wrought magnesium alloys. |
