The aim - to elucidate the changes in the structure and properties of the metal in the through production technology long-measure hard-to-deform products from aluminum alloys doped with transition metals, which includes smelting semi-their plastic deformation and heat treatment. By long-measure products, production technology which is being developed include small and medium pipe diameters and sheet products for further manufacture bent pipes and profiles. Methods: optical and electron microscopy, Auger spectroscopy, derivatohraphic study. Equipment: Vacuum oven 44-63-0067 Analyzer RHEN602 firm "LECO", an optical microscope MIM-7, 8-MIM, MIM-10 scanning electron microscope MRЭM 100, Auger spectrometer JAMP10S, Auger microprobe with field emission JAMP -9500F, derivatograph MOM 1500. Scientific novelty: a qualitative relationship between the set temperature and melt iron content in iron smelting crucibles, which are most common in domestic enterprises; found that the matererial's structure is multiphase. It's established, that the mechanical properties of hot prepared food, which made of castings that were previously homogenized higher than indicators of strength and ductility. Installed the necessity of degassing of molten smelting and preliminary homogenization pieces before hot deformation. Established that titanium degassing at 700 C for 60 s can reduce the hydrogen content to 0,16-0,26sm3 / 100 g was found that the use of modifier based on titanium carbonitrides can increase crystallization rate 6-7 times. Daily homogenization, aging in oven at 480 C for 25 hours. Made of extruded rods obtained castings with tensile strength of 416 MPa with relative elongation of 22%, which exceed passport details as the original alloy and foreign counterparts. Technology for high-quality piece of alloy system Al-Mg-Sc for the manufacture of pipe billet hot deformation is developed the first time in Ukraine. The most valuable are the results for space-space and aviation industry of Ukraine. The presence of high production of semiproducts hard-to-deform aluminum alloys have good weldability, can significantly improve the characteristics of domestic rockets and improve their competitiveness in the global market. Areas of Application of performance aircraft and space-rocket industry, mechanical engineering in general.
