FABRICATION OF LOTUS--STRUCTURED POROUS MAGNESIUM WITH GASAR PROCESS
藕状多孔金属Mg的Gasar工艺制备

Directional solidification of metal/gas eutectic (Gasar) is a novel process for fabricating porous metals with oriented pores parallel to the solidification direction. By use of the developed Gasar apparatus, porous magnesium samples with different porosities have been fabricated. In addition, this paper also studied the effects of gas pressure on porosity, pore nucleation, pore size and distribution.
