Mechanical and Microstructural Characterization of an AZ91–Activated Carbon Syntactic Foam

Our manuscript Mechanical and Microstructural Characterization of an AZ91–Activated Carbon Syntactic Foam has been published in Materials.

Abstract In this study, activated carbon (AC) particles were combined with AZ91 alloy to manufacture a magnesium syntactic foam. This novel lightweight foam has a very low density, in the range of 1.12–1.18 gcm−3. The results show that no chemical reaction occurred between the AZ91 matrix and the activated carbon particles. The mechanical properties of the foam were evaluated under quasi-static compression loading conditions, and showed a consistent trend for the energy absorption of the fabricated AZ91–AC syntactic foams. The deformation mechanism of samples was a brittle fracture mode with the formation of shear bands during the fracture of all samples.
