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
