Outline of Final Research Achievements

In order to develop the technology to form gradually distributing porosity or pore size like in vivo bone in ultra-light porous metals with more than 70% porosity, the possibility of some processes were investigated.
By the process to make gradually increasing heat temperature distribution in the foamable precursor including foaming agent, an aluminum foam with gradually distributing porosity or pore size was successfully produced.
By the process to compress partially the aluminum foam sandwich (AFS) with an aluminum sheet surfaces, the press forming complex shape into the AFS was possible even at room temperature.
