Different porosity FeCrAl tube was prepared by powder sintering with water atomized FeCrAl powder.The effect of the different sintered temperature,porosity and pre-oxidized on the ring tensile strength of FeCrAl porous metal were investigated. The results indicated that the stress-strain curve of porous FeCrAl was similar to that of brittlenss materials.Sintered temperature was more effective on the ring tensile strength.The ring tensile strength of porous FeCrAl decreased obviously with increasing porosity...
