摘要

In this study, open-cell structured AM60B magnesium alloy foam-like structures with regular architectures were successfully produced using the investment casting method. The fabricated foam samples were designed in three different cell geometries Kelvin, pyramid, and cylinder each with three distinct pore configurations. The designs were created using SolidWorks, and the model materials were manufactured with a 3D printer employing the SLA (stereolithography) process. Microstructural characterization was performed using scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD) analyses. The compression tests conducted to determine mechanical properties revealed that foams with Kelvin-type cell structures exhibited superior mechanical performance compared to the other types. This improvement is attributed to the higher surface area and lower porosity of the Kelvin structure, which is consistent with findings reported in the literature. Furthermore, the finite element model of the Kelvin foam structure was verified through compression simulations conducted in ANSYS Workbench. The corrosion behavior of open-cell AM60B magnesium foams in NaCl and Hank solution was investigated, and their corrosion rates were determined. This study aims to contribute new insights to the literature regarding open-cell AM60B magnesium foams and to identify which cell geometry and pore configuration provide the most favorable mechanical properties.
