In the article information is presented about plastic properties of the heated porous powder-like materials from ferrous powders at tests on a bend. Dependence of tangential eτ, radial eρ is set and transversal ez deformations from initial porosity of standards and grain-size distribution. Experimental confirmation of hypothesis of flat sections and unchanging position of neutral surface is got at the bend of the heated porous standards.

Keywords: plastic property, heating, porous powder-like material, bend, tangential deformation, radial deformation and transversal deformation
