    Pore Morphology and Compressive Properties of Open-Celled Porous Cu Fabricated by Using NaCl as Pore Former

    • 摘要: 以NaCl颗粒为造孔剂, 采用烧结-脱溶法制备了开孔多孔铜,对其孔隙及压缩性能进行了研究。结果表明: 所得多孔铜的孔隙多为三维贯通开孔网络结构, 孔的形貌与大小均与NaCl颗粒相似; 其弯曲断口呈现典型的韧性断裂特征; 其压缩应力-应变曲线分为明显的弹性区、平台区及致密化区3个区域, 压缩变形遵循逐层坍塌的机制, 具有较好的压缩吸能特性。

       

      Abstract: Open-celled porous Cu had been fabricated by using NaCl particles as pore former through sintering-dissolution process. The pores and compressive properties were studied. It is shown that the pores of porous Cu had 3d transfixion open-celled network structure. The shape and size of the pores were similar to those of NaCl particulates. The flexural fracture surface exhibited typical ductile rupture characteristics. The compressive stress-strain curves could be distinctly divided into three stages including elasticity, plateau and densification. The layer-by-layer collapse was the predominant deformation mechanism during compression. And the material had better compressive energy abstrption property.
