通过凝胶注模工艺制备多孔铝铜合金。研究凝胶注模工艺参数如单体含量、交联剂与单体的比例、分散剂和引发体系4个因素对坯体高度、固化时间和坯体品质3个指标的影响。其中分散剂对坯体高度，单体对坯体质量的影响最大。通过分析得出最佳工艺为：单体体积分数10%、交联剂体积分数2%、引发剂体积分数0.2%、分散剂质量1.2 g，在此条件下坯体呈现最好的品质。同时探讨工艺参数消除裂纹和形成孔结构的机理。利用压汞法得出孔直径在10~10000 nm范围内，开孔气孔率达到38.78%。

The porous Al?Cu alloy was prepared by the gelcasting process. And the effects of gelcasting conditions, such as monomer, the volume ratio of cross-linker and monomer, dispersant and redox initiating system on the height, gelling time and the quality of green body were investigated. (It was found that the dispersant and monomer played significant roles in the height and quality of green bodies, respectively.) The optimal conditions were 10% monomer, 2% cross-linker, 0.2% initiator (volume fraction), and 1.2 g dispersant, in which the green body exhibited the best quality. The mechanisms of process conditions in eliminating the cracks and forming the pores of in the five stages were proposed. Mercury porosimetry provided a description of pore diameter ranging from 10 to 10000 nm and open porosity of 38.78 %.
