427 摩擦攪拌法によるポーラスアルミニウム/緻密鋼板サンドイッチパネルの作製(溶接・接合のプロセスと評価(1),ものづくりにおける基礎研究と先端技術の融合)

Abstract

Porous aluminum is a lightweight material with high energy absorption properties. In this study, porous aluminum / dense steel sandwich panel was fabricated by friction stir processing (FSP) route. It is expected that both mixing a blowing agent into aluminum and bonding the aluminum precursor to dense steel plate can be conducted simultaneously by FSP. It was shown that sandwich panel which had high interface strength with porosity of approximately 90% was successfully fabricated at a holding temperature of 1003 K and at a holding time of 14 min 30 sec.
