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.

In the article the results of researches of plastic properties of porous powder-like materials are presented in the heated state at tests on monaxonic tension. The feature of deformation of porous standards, that consists in their practically even narrowing on all working length with a subsequent break without visible formation of neck, is marked. Dependence of deformations of lengthening and narrowing of standards is set on their initial porosity and brand of metallic powder

It is marked in the article, that at making of details of difficult form powder-like material must thermoforming of powder-like purveyances have high plasticity that would allow for certain technological terms and chart tensely - the deformed state to provide their shaping of zero-defects. Presented taking about the method of test of the heated porous powder-like standards from ferrous powder on a bend. The constructions of press-form are described for cold-press of powder-like standards and adaptation for their dynamic bend in the heated state.
