In this research, metal syntactic foams (MSFs) were manufactured using counter-gravity infiltration casting. Expanded perlite (EP) and Activated carbon (AC) particles were used as fillers inside a ZA27 alloy matrix. MSFs were manufactured in different aspect (height/diameter) ratios of 0.5, 1 and 1.5. The dynamic compression of these samples was carried out at 284 mm/s. Infrared thermography was employed to monitor the plastic deformation of samples. The results indicate a distinct influence of the particle type and sample size on the deformation mechanism and mechanical properties of MSFs. EP-MSFs mostly deformed in layer-by-layer mode whereas AC-MSFs experienced shear fracture. In EP-MSF, changing the aspect ratio altered the plateau stress of the samples. In AC-MSF, the aspect ratio affected the initial compressive strength without any significant change in plateau region.
