The closed-cell aluminum alloy foams were fabricated by the molten body transitional foaming process. In this research, the closed-cell aluminum foams were successfully fabricated with different zinc contents (4, 8, and 12wt%) using the melt-foaming method and blowing agents. Calcium was used to increase the melt viscosity and CaCO₃ was used as a foaming agent. Uniaxial compressions tests were performed on the foams to investigate the effects of zinc addition on the mechanical behavior of fabricated Al–Zn foams. The effects of zinc additions on the foam properties such as density, porosity, pore diameter, yield strength, plateau stress, and energy absorption were investigated. According to the X-ray analysis results, the reaction between Al–Ca–Zn leads to the formation of oxide phases in the melt and increases the melt viscosity and also the cell wall thickness. Foam with 4wt% Zn has a good yield strength and longer plateau region than pure aluminum foam due to the uniform cell structure. The foam density and the absorbed energy per unit volume of Al–Zn foams increase with increasing zinc content to foams.

采用熔体过渡发泡工艺制备闭孔铝合金泡沫。在这项研究中，使用熔融发泡法和发泡剂成功制造了具有不同锌含量（4、8 和 12wt%）的闭孔泡沫铝。钙用于增加熔体粘度和 CaCO ₃用作发泡剂。对泡沫进行了单轴压缩试验，以研究锌添加对制造的铝锌泡沫机械性能的影响。研究了锌添加量对泡沫特性的影响，例如密度、孔隙率、孔径、屈服强度、平台应力和能量吸收。根据 X 射线分析结果，Al-Ca-Zn 之间的反应导致熔体中氧化物相的形成，增加了熔体粘度和孔壁厚度。由于均匀的泡孔结构，含 4wt% Zn 的泡沫具有比纯泡沫铝更好的屈服强度和更长的平台区。Al-Zn 泡沫的泡沫密度和每单位体积吸收的能量随着泡沫中锌含量的增加而增加。
