The bimetallic iron-bronze powder material obtained by wedge hot compaction is considered. A hypothesis is formulated, confirmed by the results of experimental studies, about the determining effect of volumetric deformation of the powder material of the iron base in the process of wedge hot compaction. The concept of an indicator is introduced and a 2D Impulse model of the quality of consolidation of heterogeneous powder layers is constructed from the absolute values of the volumetric deformation of the iron base. As a result of the analysis of the constructed 2D Impulse model for the transition zone of a bimetal obtained by technology including sintering, the absolute value of │0.21│ of the critical volumetric deformation was established, which ensures the transition from satisfactory to good quality of consolidation, taking into account the introduced quality scale. For technology that does not involve sintering, the absolute value of │0.171│ of critical volumetric strain, equal to the parameter "c" of the model, characterizes the transition from unsatisfactory to satisfactory quality of consolidation.

This paper presented the study of the mechanochemical activation powder mix in dry and liquid grinding media, accompanied by agglomeration of the particles. It Is shown that when agglomerate particles having a bimodal size distribution is forming during the treatment in a dry grinding media and partially (2 wt % ) decaying at grinding by pestle in mortar. The transition to liquid grinding media is leading to a unimodal size distribution and increasing dispersion of the agglomerated particles, characterized by secondary agglomerating when using the alcohol and destruction when using activation in saturated aqueous solution of boric acid. Inherited effect mechanical activation parameters on the compaction process during cold compaction and hot stamping has been determined. Application treated in a high energy mill in an grinding media saturated aqueous H3BO3 Al-Si powder mix results in the formation of moldings with low cold-pressing relative density (0.735) and the activation of the hot stamping compaction (|εh| = 0,592) providing production of hot-deformed powder material with increased mechanical properties.
