The compression strength is well characterized by the ability to transfer compressive stresses through porous materials. It can be determined by examining the material on the endurance machine in a single-axis compression test. The test was made on a strength machine Zwick / Roell Z100. Cylindrical specimens, made from Fe powder (ASC 100.29 and DISTALOY SE) and Fe powder with carbon addiction, about dimensions H =14 [mm], d = 16 mm, have been subjected to compression. The initial force was 100 N, while the displacement was 1 [mm / min]. Direct compressive strength (Rm) was obtained by examining the maximum value of compressive force of data range for deformation stress function. The diversity in the microstructure and porous structures properties can lead to fluctuations in the results during the endurance tests. The divergence of the Young's modulus of the aluminum porous material can vary from 5 to 30 %, and a compressive strength from 5 to 15 %. The Young's modulus was calculated on the basis of the range of 0.25 - 0.75 stresses in the linear range by dividing the stress by the deformation.Keywords: Metallic foam, sintering Fe foam, up-settings characteristics
