Research Advancement of Porous Fiber Metals

Porous fiber metals are a kind of metallic materials which have a through-pore structure by forming and sintering.They have the advantages of light weight,high surface area and high specific strength.They are widely used in engineering field.This paper described the progress and application of porous fiber metals.And analysed the progresses of titanium fiber porous materials,nickel fiber porous materials,FeCrAl fibrous porous materials,copper fiber porous materials and stainless steel fiber porous materials,and prospected their further development.
