Abstract 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.

Key words: porous metal eutectic solidification Gasar process
