In this study, highly porous pure aluminum material with cellular structure was fabricated via powder metallurgy route using a space holding technique with the addition of boric acid powders as pore-forming agents. Boron products, namely, the boric acid, were used as novel pore-forming agents. Aluminum powders with high porosity of ~50% were successfully produced. The experiments were focused on investigating the effects of such parameters as compaction pressure and sintering temperature on the final properties of fabricated samples by determining their optimum values. Quasistatic compressive behaviors of the obtained highly porous materials were examined at a strain rate of 10^–3 sec^–1. The results show that the most suitable compressive properties of the highly porous states were obtained for the samples cold-pressed under 630 MPa and sintered at 620°C for 3 hours. According to the stress-strain behavior of the high-porous states, there is a plateau region with nearly constant flow stress and a large strain of about 70%. The densities of these high porous states were approximately 1.0 g/cm³, and the mean cell sizes amounted to about 0.6 mm. Using boric acid (H₃BO₃) powders differs from conventional processes in terms of superior comprehensive mechanical properties with static compressive strength and energy absorption of 18 MPa, and 12 MJ/m³, respectively.

在这项研究中，采用空间保持技术，通过添加硼酸粉末作为成孔剂，通过粉末冶金方法制造了具有多孔结构的高孔隙率纯铝材料。硼产品，即硼酸，被用作新型的成孔剂。成功生产出具有约50％的高孔隙率的铝粉。通过确定样品的最佳值，实验着重于研究压实压力和烧结温度等参数对加工样品最终性能的影响。在10 ^–3 sec ^–1的应变速率下检查了所获得的高度多孔材料的准静态压缩行为。。结果表明，对于在630 MPa下冷压并在620°C烧结3小时的样品，获得了最合适的高多孔态压缩性能。根据高孔隙状态的应力-应变行为，存在一个平台区域，该区域具有几乎恒定的流动应力和大约70％的大应变。这些高多孔状态的密度为约1.0g / cm ³，并且平均孔尺寸为约0.6mm。使用硼酸（H ₃ BO ₃）粉末与常规方法的不同之处在于具有优异的综合机械性能，静态抗压强度和能量吸收分别为18 MPa和12 MJ / m ³。
