| Abstract Scope |
The application of wrought magnesium alloys has been limited due to the difficulty of achieving excellent room-temperature formability and high strength simultaneously. One approach to overcoming this issue is developing heat-treatable alloys. This presentation will discuss strategies for designing heat-treatable alloy sheets that are as formable and strong as 6XXX series aluminum alloys.
Among age-hardenable magnesium alloys, Mg-Ca-X (X = Zn, Al, etc.) low-alloys are the most promising as heat-treatable alloys. Adding Zn into Mg-Ca alloy results in excellent formability because solution treatment causes the (0002) poles of the grains to tilt away from the sheet's normal direction. Subsequent artificial aging leads to substantial strengthening due to the dispersion of Ca-Zn co-clusters and solute segregation to dislocations. These insights have led to the development of an Mg-3Zn-0.5Ca-0.5Zr alloy that is highly formable and strong with an Index Erichsen value of 8.0 mm and a yield stress of 240 MPa. |
