| Abstract: | The structure and its control of the porous aluminum prepared by a special pressure infiltration process was studied ,for which a model for calculating the porosity of porous metals was developed. The experiment and calculation results show that they have a good agreement. It was observed that the porosity of the metals was able to be controlled by the compactness of the fillers and the degree of pore opening among them. The porous aluminum with expected pore structure was reliably obtained. |
