Abstract
Pore structure control methods for porous FeAl intermetallics were studied in this paper based on pore formation mechanism. A large range of pore structure parameters can be obtained through fabrication parameter adjustment in porous FeAl preparation procedure. Open porosity and maximum pore size of porous FeAl have a direct proportional relationship to the powder size of raw materials and an inversely proportional relationship to the pressing pressure. The relationship between maximum pore size (dm) and raw material powder size (dp) can be determined as dm=0.40dP. Open porosity and maximum pore size decrease with increasing holding time at solid diffusion reactive procedure. The quantitative relationship between open porosity (θ) and holding time (t) at 600 °C is θ=49.7−0.1t(60≤t≤240); the quantitative relationship between maximum pore size (dm) and holding time (t) at 600 °C is dm=20.3−0.065t(60≤t≤240).
