Abstract—The continuous extrusion (the Conform method) of a noncompact aluminum material of the
Al@@Mg system is investigated. The experimental data on the variation in temperature and energy-power
process parameters are found. An analysis of the variation in temperature and hydrostatic pressure in the zone
of the deformation treatment is implemented. Seven zones which qualitatively characterize the extrusion of a
noncompact material are revealed during this analysis. An essential nonuniformity of the hydrostatic pressure
in the deformation region, which governs the inhomogeneity of the properties of prepared billets, is observed.

Keywords: continuous extrusion of metals, modeling, noncompact materials, temperature, hydrostatic pressure
