| Abstract: | New-type sheets of Mg-6Li-3Zn and Mg-11Li-3Zn alloys were prepared by melting/casting,homogenization and hot/cold rolling.Their mechanical behavior at room temperature,microstructures after hot rolling and lithium loss phenomenon during hot rolling were all investigated.The tensile strength and true strain of fracture at room temperature of the two alloy sheets were measured as 208 MPa/0.13 and 170 MPa/0.375,respectively.The room-temperature relationship between true stress and true strain revealed that the... |
