多孔質合金의 製造에 關한 硏究

Abstract

Al-Si-Mg-Ti系 合金의 melt를 600℃ 부근에서 機械的으로 攪拌하여 多孔質 金屬材料를 얻었다. 合金의 組成은 Si=5∼10%, Mg=5∼10%, Ti=1∼3% 범위였으며 發泡體의 氣孔度는 최대 77%, 겉보기密度는 최저 0.62g/㎤에 到達되는 것을 얻을 수 있었다.

An inprovement in making a metal foam body is provided which involves mechanical stirring aluminum alloys at 600℃, of which preferred adding elements are Si=5∼10%, Mg=5∼10%, Ti=1∼3%, to the molten mixture from whieh the foam has max. 77% of orosity and min. 0.62g/㎤ of apparent density.
