Comparison Through Image Analysis Between Al Foams Produced Using Two Different Methods

摘要: Several methods are available for making metal foams. They allow to tailor their mechanical, thermal, acoustic, and electrical properties specific applications by varying the relative density as well cell size morphology. Foams have a very heterogeneous structure so that may show large scatter. In this paper, an aluminum foam produced means of foaming powder compacts another one prepared via infiltration process were analyzed compared. Image analysis has been used useful tool determine size, morphology, distribution cells in both foams correlate morphology with considered manufacturing process. The results highlighted strictly dependent upon method. This paper shows how some standard 2D morphological indicators be usefully adopted characterize whose derives from
