The sintering and dissolution process (SDP) is a novel method for cost-effective manufacture of net-shape aluminium foams. The potential benefits of SDP are derived from its capability of accurate control over the cell morphology, size, distribution and porosity. It is particularly suitable for producing fine-and open-celled aluminium foams with medium relative densities. The as fabricated foams have great potential for applications in a wide range of structural and functional products, especially as energy and sound absorbers. This paper describes the principle and operating conditions of SDP,demonstrates the microstructural and mechanical properties of the resultant aluminium foams, and discusses its advantages and limitations in comparison with the other manufacturing methods currently available.
