21404 Pore Size Distribution of Porous Aluminum Fabricated by Friction Stir Route Precursor Method

Abstract

Recently， porous aluminum has attracted special interest as a new fhnctional material ． However ， the application of porous alu 血 nu 皿 rema 血 s limited due to high ・ cost fabrication and low produetiVity ． To overcome these problems ， the authors proposed a new fabrication method by using f士iction stir processing ( i． e ． FSP precurser method ) ， In this study ， the pore structures ef porous aluminum fabricated by the method are observed through X − ray CT ． ln the porous aluminum by FSP precursor method
