采用金属气体共晶二维定向凝固的方法（二维Gasar）制备了放射状规则多孔金属。对放射状规则多孔金属的孔分布结构进行建模，论证了模型的合理性。研究了气泡形核、气孔合并和中断对结构的影响机制，并且定量分析了在这些机制的作用下结构参数发生的改变。利用模型和实验结果计算了实际制得试样中气孔形核、合并和中断的发生概率。
Regular porous metal with a radial pore distribution is produced by precipitation of supersaturated gas when the melt is bidirectionally solidified. A model was proposed to describe the ideal pore distribution of radial-type regular porous structure and rationality of the model was proved. This model can describe the effects of pore nucleation, pore coalition and pore interruption on structural characteristics and their quantitative relation can be deduced from the model. Probability of pore nucleation, pore coalition and pore interruption in the samples was also calculated.
