摘要:

使用自制的Gasar装置制备出Cu、Mg和Ni三种藕状多孔金属, 将理论计算与实验结果相结合研究了材料的凝固速率对多孔结构的影响。结果表明, 对于三种多孔金属, 随着气泡半径的增大气泡的上浮速率逐渐增大。仅当金属凝固速率最大值在气泡上浮速率的范围内, 才能制备出有大量规则气孔的藕状多孔结构。

Abstract：

Lotus-type porous Cu, Mg and Ni were fabricated by a mould casting technique in hydrogen gas atmosphere. The effect of solidification rate on the structure of the lotus type porous metals was comparatively investigated by theoretical calculation and experiments. The results show that the increase of bubble radius results in an increase of bubble rising velocity for Cu, Mg and Ni. A suitable ordered porous structure can be obtained only when the maximum solidification rate is in the range of bubble rising velocity.

Key words： metallic materials Gasar lotus-type metals unidirectional solidification solidification rate pore structure
