The tensile properties of experimentally produced Mg-6Li-1Zn, Mg-9.5Li-1Zn and Mg-12Li-1Zn alloy thin sheets at room temperature are investigated in this study. Uniaxial tension tests are carried out for various strain rates between 1.4 x 10(-5) and 8.3 x 10(-2) s(-1), and the microstructural and textural changes during the tests are examined. The Mg-6Li-1Zn sheet is composed mainly of the alpha (hcp) phase and inferior to the other sheets in ductility. The beta (bcc) phase is dominant in the Mg-9.5Li-1Zn and Mg-12Li-1Zn sheets, and they have a considerable sensitivity to strain rate. It is observed that the grains are elongated with textural change mainly in the beta phase at low strain rates, and the Mg-9.5Li-1Zn and Mg-12Li-1Zn sheets have sufficiently high ductility at low strain rates. The Mg-9.5Li-1Zn sheet composed of (alpha + beta) two phase is superior to the Mg-12Li-1Zn sheet of beta single phase in the tensile strength.
