High speed superplasticity has firstly realized at room temperature with Zn-Al alloy nano-sized. The Zn-Al alloy has some fine property in coMParison with the low yield point steel, which has low hardening and large ductility. And it doesn't contained Pb. But, when the Zn-Al alloy deformed, local deformation is occurred by it's low hardening, and the deformed part is broken locally. In this paper, It is presented to design the seismic damper made of the Zn-Al alloy without the local deformation. Therefore, ecological and high performance seismic damper has been successful to developing, so-called "maintenance-free seismic damper"
