The growing interest in the process of hydrostatic extrusion is reflected by numerous publications on experimental results, fundamental researches and theoretical studies (e. g., [1] to [20]). In recent years it was the increasing demand for new materials and semiproducts with special cross-section dimensions and properties that substantiated the necessity of defining the application of hydrostatic extrusion in the field of non-ferrous metallurgy. Thus, it is the aim of the researches carried out with the experimental hydrostatic extrusion press type QEH 12 recently installed by the Swedish company ASEA in the Forschungsinstitut für NE-Metalle Freiberg of the VEB Mansfeld Kombinat “Wilhelm Pieck” to solve problems of materials and deformation engineering and to develop new technologies of producing special semiproducts from non-ferrous metals.
