pores. The overall porosity and porosity of open pore of the sintered porous magnesium increase with the increase of added spacer material, while decrease with the increase of the molding stress. The mechanical properties of sintered porous magnesium increase with decreasing addition of spacer material and increasing molding stress. Key words: porous magnesium; powder metallurgy; spacer material......

acoustic absorption performance. Key words: porous titanium fiber material; acoustic absorption; heat transfer; pool boiling 1 Introduction Nowadays, noise is one of the three major environmental pollution... management. The main solution is to use porous material with homogeneously distributed internal fine through-open pores to absorb the noise [5-8]. Porous metal materials possess many new excellent features......
Effect of porous structure on mechanical properties of C/PLA/nano-HA composites scaffold LIAO Xiao-ling(廖晓玲)1,2, XU Wen-feng(徐文峰)3, WANG Yuan-liang(王远亮)1, JIA Bi(贾 碧) 2, ZHOU Guan-yu(周冠瑜)2...; Abstract: Nonporous and porous C/PLA......
, the loading conditions of these porous materials were further studied for various strut failure modes from different loading. The results show that these failure modes are relative to the material indexes, porosity and loading magnitude, and these relationships can be correspondingly expressed by the specific mathematical equations. Key words: foamed metal; porous metal; porous material 多孔金属构件作为一种性能优异的工程......
titanium presents diminished mechanical properties compared with the solid material, and porous titanium implant helps to reduce the stiffness mismatch between implant and bone tissue, thus reducing ‘stress shielding’ and achieving stable long-term fixation[4]. A porous implant material with adequate pore structure and appropriate mechanical properties has been sought as the ideal bone substitute......
applications as the strength of bulk porous material decreases linearly with the increase of porosity. To overcome the above concerns, it is suggested to fabricate a metallic porous coating...

material. Methylcellulose and paraffin are used as porogen. The influence of porogen type and copper powder morphology on the property of copper porous materials is investigated as well. The results show... and controllable, so it is more conducive to the development of high-performance porous metal material [12–13]. In this study, copper porous materials have been manufactured by the method of adding......
