説明

We used a new method to fabricate micro porous bell-shape metal from glass microcapsules and liquid metal. Each pore structure behaves as a micro-bell. This metal, which is more than 20% lighter than bulk material, also shows a unique characteristic: high-frequency oscillation is greatly attenuated when propagated in its medium. This method offers great potential for size, shape, and conformation control, with changed the attenuation characteristics achieved merely by changing the mixing technique. In present study, we could fabricate some kinds of micro porous bell-shape metals with different bell-shape structure only by changing microcapsule size. Then, the attenuation characteristics and mechanical behaviors were measured for fabricated micro porous bell-shape metals.
