| 1 | Preparation of big size open-cell aluminum foam board using infiltration casting显示文摘This paper presents an infiltration casting technique for manufacturing big size open-cell aluminum foam boards.The principle and key technologies of infiltration casting are also analyzed.Based on the previous practice of the small size aluminum foam production,the die for preparing big size aluminum foam boards is designed and manufactured.The experiments on aluminum boards of 300 mm×300 mm×(20-75)mm,with the pore size ranging from 1.0 to 3.2 mm and average porosity of 60%,have been performed.The experimental results show that a reliable infiltration process depends critically on the pouring temperature of the molten Al-alloy,the preheated temperature of the mould and salt particles and vacuum.Current research explores the possibility of large-scale manufacturing and application of the aluminum foams. | wang Lucai Chen Yuyong Wang Fang Wu Jianguo You Xiaohong | 2008 | China Foundry2008，5，4： | 1 |

| 3 | Preparation of open-cell metal foams by investment cast显示文摘Metal foams are a new kind of materials with low densities and novel physical, mechanical, thermal, electrical and acoustic properties. They can be divided into closed and open cell structures. In this paper the open cell structures, called sponges, were treated. A new technique to manufacture sponges by plaster investment casting was described. Experimental results show that it is essential to make a sound plaster mould by casting plaster slurry into the polyurethane foams and infiltrate the open channels of the baked plaster mold by molten metal. The optimal processes include plaster slurry preparation, plaster mold baking, and molten metal infiltration. The sponge sample with porosity of 97% is presented. | Lucai WANG Haijuan LI Fang Wang Jianfu REN | 2005 | China Foundry2005，2，1： | 0 |
| 4 | Defects in aluminum foam with superfine open-cell structure显示文摘The infiltration casting process for producing aluminum foam includes three steps:preparingprecursor using NaCl particles,infiltrating molten aluminum and cleaning NaCl precursor.Defects occur during thepreparation of aluminum foam with superfine open-cell structure,and influence the pore structure and performanceof aluminum foam materials.The types of the defect and their forming mechanisms are analyzed in this paper.The defects include point defects and linear metal defects,and are caused by the defects in salt precursor and theinsufficient infiltration of molten aluminum into precursor.With the choice of proper precursor preparation methodand infiltration process parameters,the complete aluminum foam with superfine pores could be achieved. | Wang Fang Zhang Zhimin Li Baocheng Wang Lucai | 2008 | China Foundry2008，5，3： | 0 |
