The mechanical properties of Zn-22% Al alloys were measured with the low-frequency forced vibration mode. It was observed that a typical transformation internal friction peak was associated with eutectoid decomposition. A relaxation peak in the complex elastic modulus M2-T curves with an activation energy of 100±1.2kJ/mol was observed at the low-temperature side of the eutectoid decomposition peak. It was deduced that the relaxation process was related to the diffusion process of Al atom along the αβ phase boundary and αα crystal boundary.
