Abstract

By use of the radial solidification process of metal/gas eutectic, at an atmosphere of high-pressure hydrogen or gas mixture of hydrogen and argon, porous magnesium samples with radial pore distribution have been fabricated successfully through heat transferring in the radial direction. The influence of the gas pressure on the average pore diameter and average porosity was investigated. A model has been proposed to describe the evolution trend for mean pore diameter in structure of radial porous metal and the rationality of this model was proved. In addition, this paper studied the effects of pore nucleation, pore coalition and pore interruption on structural characteristics both from theoretical and experimental points.
