The paper analyzes the length variety of the crystal gain and sub-crystal gain ofmagnesium alloy materials during the strain amplitude augmentation in the linearity stage of thematerial deformation, and then based on G-L model derives the mathematical model of the dampingvariety durign the strain amplitude augmentation in the linearity strain stage of the magnesiumalloys. Consequently, magnesium alloy damping mechanism is studied theoretically. It is provedthat the magnesium alloy material has the advantages of high damping capacities. In addition, acomparison test in terms of damping performance is made between magnesium alloy and otheralloys, which further confirms the high damping of magnesium alloy and the rightness of thetheoretical deduced conclusion. © (2013) Trans Tech Publications, Switzerland.
