Abstract
Open-cell porous aluminum (Al) was fabricated by friction powder compaction (FPC) process without using external heat sources In this process, powder mixture of Al powder and sodium chloride (NaCl) powder as spacer particle was used as starting material The compacting and sintering of the mixture were conducted only by rotating tool plunged into a die and mixture NaCl was removed by placing the sintered mixture m water In this study, pore structures of obtained porous Al were nondestructively observed by X-ray CT In addition, a relationship between porosity and compression properties of obtained porous Al were investigated
