In this study, aluminum foam made of Etial 160 (AlSi₈Cu₃Fe) was produced using vacuum die casting method and the process of artificial aging was implemented. The mechanical properties and microstructure of the fabricated foam were investigated. Results of the present study indicate that the artificial aging process has a significant effect on mechanical behavior of aluminum foam. The microstructure, surface morphology, hardness and composition of the Al alloy foam were investigated using scanning electron microscopy (SEM), the Vickers hardness test and X-ray diffraction method. The SEM–EDS and the Vickers hardness measurements show that the best temperature for precipitation hardening is 170 °C for 30 min.

在这项研究中，使用真空压铸法生产了由Etial 160（AlSi ₈ Cu ₃ Fe）制成的泡沫铝，并实现了人工时效工艺。研究了所制备泡沫的机械性能和微观结构。本研究的结果表明，人工时效过程对泡沫铝的机械性能具有重大影响。采用扫描电子显微镜（SEM），维氏硬度试验和X射线衍射法研究了铝合金泡沫的显微组织，表面形貌，硬度和组成。SEM-EDS和维氏硬度测量结果表明，沉淀硬化的最佳温度为170°C，持续30分钟。
