| description | Closed-cell aluminium foams with different compositions have been manufactured starting from powders and also characterized from a morphological point of view and by means of compressive tests in order to determine mechanical properties. Circularity, equivalent diameter, and average porosity area of such foams have been calculated from the analysis of cross-sections as well specific energy absorption in compression tests. Samples with a higher amount of blowing agent (TiH<sub>2</sub>) have the highest energy absorption while samples with a higher amount of stabilizing agent (SiC) exhibit good foam properties overall (best compromise between morphology and energy absorption). The analysis of morphological properties, such as area, circularity, and equivalent diameter, can provide a better understanding of the foam’s structure and porosity––parameters which can be manipulated to enhance the foam’s properties for specific applications, both structural and functional. |
