The fabrication of cellular metallic materials is introduced. Emphasis is placed of the studies of mechanical properties of cellular metallic materials. They are mainly concerned with influences of micro-defects to the mechanical behavior of cell-structure, analyses of cell collapse, responses of cell morphology to applied loads, experimental explanations of the origin, development of deformation bands and a theoretical model of open-cell structure of the materials. Based on the above summary, some discussions and future development trends are presented. Finally it puts forward a computer morphologic analysis method and image processing technique that will be widely applied to testing the mechanical behavior of cell instabilization.
