This article proposes for consideration the hot-deformed powder materials spliced surfaces area quantitative characteristics’ experimental determination. This study analyzes the spliced surfaces’ microstructures formation at various stages of obtaining hot-deformed powder materials. The features of the deformation processes during the formation of materials by hot working with pressure are considered. The nature of the splicing surfaces’ boundaries on the objects under study, as well as the process of pore healing during the compaction of moldings based on steel from two types of charge based on coarse and fine iron powder with different porosities, is traced. In the course of the work carried out, the selected iron powder particle size certain influence moment on the values of micro- and sub-micropores, surfaces of interparticle adhesion, inter- and intragranular adhesion is observed [1-3].
