抜粋

Fabrication of a graded pore structure in porous aluminum alloys is attempted by locally changing gas generation in the powder compacts during firing. Layers of Al-Si powder mixtures with a foaming agent in different amounts are compacted into cylindrical precursors and heated up in a furnace with tubular molds. The effects of mold sizes and layer combinations on the macroscopic foaming behavior, i.e. the shape change and the pore formation in the powder compacts, are examined by numerical analysis as well as experiment. It is confirmed that pore distribution can be produced by stacking different layers, but the final layered structures is affected by the distortion due to gravity.
