507 発泡アルミニウムの表面緻密層成形における摩擦撹拌インクリメンタルフォーミングと圧縮加工の比較

抄録

The friction stir incremental forming method was possible to fabricate the solid skin layer with thinner than 0.4mm on the surface of closed-cell type aluminum foam (Shinko Wire Company, Ltd.: ALPORAS, relative density 0.1, mean diameter of pore φ4 mm) without causing fracture the inside The area fraction of metal matrix at the surface was obtained as about 80% in forming conditions of tool rotation rate of higher than 8000 rpm and tool feed rate of 60mm min^<-1> The solid skin layers fabricated the friction stir incremental forming, incremental hammering and uniaxial compression methods were compared
