As-cast and solution heat-treated samples were tested to investigate the compressive properties of the ZA27 syntactic foam. To this end, quasi-static compression tests were conducted. In addition, microstructural analysis of the as-cast and heat-treated syntactic foams was carried out using scanning electron microscopy. The results indicate that the heat treatment alters the microstructure of the ZA27 alloy matrix from a multiphase dendrite to a spheroidized microstructure with improved ductility. Moreover, the heat treatment considerably enhances the energy absorption and plateau stress (σ_pl) of the syntactic foam. Optical analysis of the syntactic foams under compression shows that the dominant deformation mechanism of the as-cast foams is brittle fracture. In comparison, the heat-treated samples undergo a more ductile deformation.]]> Tue 22 Jun 2021 18:29:06 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:40745 Thu 15 Feb 2024 10:39:47 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33288 Fri 28 Sep 2018 15:54:18 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33286 Fri 28 Sep 2018 15:47:18 AEST ]]>
