Summary

One of the authors has recently succeeded in producing a thin sheet of a Mg-8.5Li-1Zn alloy with a thickness of 0.6 mm. In this study, the formability of the sheet at room temperature is investigated. Uniaxial tension tests are carried out for various strain rates, and the microstructural and textural changes during the tests are observed. It is found that the sheet has a considerable sensitivity to strain rate even at room temperature. Furthermore, some fundamental press-forming tests, such as deep drawing, bore expanding and Erichsen tests, are carried out, and the effect of the strain rate sensitivity on the formability is discussed.
