摘要：

Two porosity models of porous Al alloys with different pore types (ball and polygon shape) were established. The experimental results coincide well with theoretical computations. The porosity of Al alloys (Pr-c) consists of three parts, porosity caused by preform particles (Prp), additional porosity (Pr-a), and porosity caused by solidification shrinkage (Pr,). Prp is the main part of Pr-c while Pr-a is the key for fabricating porous Al alloys successfully in spite of its little contribution to Pr-c.
