摘要
在泡沫铝合金材料的渗流铸造中，多孔体的制作是获得良好泡状组织的基础，多孔体与模具的预热温度、铝合金的浇注温度是保证泡状金属材料成型的关键。通过对多孔体粒子粒径与充型压力关系的研究后认为：多孔体粒子的大小与充型压力呈线性关系，充型压力随着粒径增大而降低。
aking porous matrix in the base to obtain the better form structure,The preheating temperature of porous matrix and patten and pouring temperature aluminum is the keypoint to guarantee the formation of foam metal material.Through the study on the relationship between grain size of porous matrix and filling pressure,it is found that grain size of porous matrix is linear with filling pressure,and filling pressure is reduced along with grain size increasing.
