Quantitative characteristics of area of splicing surfaces of hot-deformed powder materials

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