All rights reserved.In this study, the macrostructural and microstructural characterization as well as compressive strength of pure Zn and Zn alloy (ZA27) foam materials produced by the addition of 50% boric acid (H3BO3) as a space holder by powder metallurgy method were investigated. Pure Zn foams were pressed at different pressures of 300, 420 and 630 MPa and Zn alloy foam materials pressed at 630 MPa pressure and both pure Zn and Zn alloy foam materials were sintered at 350 ° C for 70 minutes. The mechanical behaviors of the foam materials obtained successfully from these foams were investigated at a compression rate of 0,5 mm/min. The results show that the yield stress and plateau stress for the ZA27 alloy foam material were 7 MPa and 6 MPa, respectively. Pure Zn and ZA27 alloy foam samples containing 40% and 46% porosity were successfully produced with average cell sizes of 85 μm and 600 μm, respectively. The morphology and chemical composition of the phases in the foam samples were investigated using Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDX) and X-ray diffraction (XRD).
