Microstructural studies confirmed that no relevant chemical reaction occurred within the foam, in particular in the vicinity of the particle-matrix interfaces. The mechanical properties of the produced FG-MSF were evaluated using quasi-static compression testing. The results showed that the deformation mechanism of the FG-MSF is a mixed mode and varies between the two different filler layers. The energy absorption of the FG-MSF sample was increased compared to uniform syntactic foams containing only a single particle filler.]]> Tue 22 Jun 2021 18:36:18 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37904 −3. 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:37920 Tue 14 May 2024 10:08:04 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:52383 Tue 10 Oct 2023 14:44:58 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:35236 -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.]]> Tue 02 Jul 2019 15:14:51 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37913 Thu 24 Jun 2021 11:26:55 AEST ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:44842 Mon 24 Oct 2022 10:13:34 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37955 Fri 17 Nov 2023 11:42:01 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:54693 Fri 08 Mar 2024 11:59:44 AEDT ]]> https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:49148 Fri 05 May 2023 12:14:03 AEST ]]>
