Abstract

A new approach to the formation of mechanical properties of iron-based powder materials is proposed. The approach is based on model ideas of the structure formation from powder mixtures in a bulk state under applied compacting pressure. It is found that with increasing (decreasing) porosity ranging from 5 to 25%, the structure of compacted powder mixtures (compacts) changes through alternation of meso- and submesostructural states.
