| Summary: | Mg-（5-22）（mass fraction, %）Li alloys with Zn addition were produced and studied. The density of studied alloys is 1.19- 1.62 g/cm^3. It is found that the alloy has excellent cold-workability and can be rolled to thin sheets at room temperature. The tensile tests were carried out at various tensile temperatures and strain rates. It is remarkable that the superplasticity occurs during uniaxial tensions at 150℃. In addition, the sheet is very sensitive to strain-rate even at room temperature. The age-hardening of the sheets at room temperature and 50℃ was investigated. The hardening may be caused by the precipitation of MgLi2Zn phase, and overaging occurs owing to the phase transformation from MgLi2Zn to MgLiZn observed by X-ray diffractometry. |
