摘要
A new method based on the Kirkendall effect is developed to fabricate Ti-Al porous alloys with open pores and adjustable pore size. This novel porous material (microstructures shown in the figure) has excellent pore size stability and outstanding corrosion and oxidation resistance. These exceptional advantages of fabricated Ti-Al porous alloys make them an ideal filtration candidate for rugged environments.
