PURPOSE : A Mg-Zn base wrought magnesium alloys having superior formability at a high strain rate in a low temperature and a manufacturing method of the alloy sheet is provided to increase the strain at a low temperature and stabilize a fine structure by adding a small amount of elements.CONSTITUTION : A Mg-Zn base wrought magnesium alloys having superior formability at a high strain rate in a low temperature comprises zinc 3.5 weight%%, iron, scandium, calcium, silver, titanium, zirconium, manganese, silicon, nickel, strontium, copper, aluminum, tin, rare earth materials or alloy consisting of rare earth materials. A recover process and recrystallization are begin at temperature of 120~140°C. A specific- base slip is activated.COPYRIGHT KIPO 2011
