The paper studies the effect of hafnium and erbium additives on microstructure formation during heat treatment aluminium alloys with a high magnesium content additionally alloyed scandium zirconium. For study, ingots scandium, in ranges 0.03–0.16 % 0.05–0.16 %, respectively, were produced by casting steel chill mould. After casting, samples treated at temperature 370 440 °C holding time 2 to 96 h. Changes microhardness depending studied. 1590-3 1590-4 as-cast condition after for 48 h, fine...
The study addresses the effect of magnesium and other alloying elements on rolling “β-fiber” texture formation during hot deformation aluminum alloys. For study, flat cast ingots from three alloys with variable content were deformed in a Gleeble testing unit different parameters thermomechanical treatment. Immediately after completion deformation, samples quenched using an automatic cooling system microstructure crystalline was analyzed by optical microscopy X-ray analysis. analysis...
This paper addresses the study of complex effect alloying elements (magnesium, manganese, copper and zirconium) on changes in magnesium-rich aluminum alloy composition, fine coarse particle size number, recrystallization characteristics mechanical properties. The data obtained made it possible to analyze change chemical sizes intermetallic compounds dispersoids depending content. composition driving force number nuclei was studied. It established that addition leads grain refinement,...
The study investigates the effect of casting speed on solidification microstructure aluminum alloy Al0.3Mg1Si with and without additions zirconium scandium. Casting was carried out in steel, copper, water-cooled chill molds a crystallization rate 20 °C/s, 10 30 respectively. For each mode, grain structure investigated by optical microscopy intermetallic particles were scanning transmission microscopy; addition, measurements microhardness electrical conductivity out. An increase promotes...

Introduction. High-magnesium aluminum alloys are widely used in the automotive, building and aerospace industries due to its low specific gravity high strength. The characteristics of such can be improved by small additions scandium zirconium. However, is very expensive, so new generation amount tended reduced. In recently developed 1590 alloy, this was achieved addition erbium hafnium. objective paper study effect hafnium concentrations on modification cast structure alloy at solidification...
The study addresses the effect of 1580 and 1590 alloys cold rolled strip annealing practices on alloys’ grain structure mechanical properties. alloy differs from by hafnium erbium additions. Samples such were produced casting into a steel mold. After that they homogenized during 4 h at 440°С. Then samples hot 440°С, with further rolling to 2 mm, cumulative percentage reduction equal 66%. was annealed temperature ranging 330 440°С 1 soaking. sizes morphology Al3Sc strengthening nanoparticles...
The evolution of texture in the AlMg6Mn0.7 (1565 ch) alloy throughout entire cycle its thermomechanical treatment has been studied. Using this as an example, a new way is shown to control development, which applicable alloys with high magnesium content. An integrated approach applied, including optical and electron microscopy, well X-ray diffraction analysis, determination mechanical properties modeling using algorithms crystallographic plasticity theory. All stages have studied, namely...
The paper presents the results of a computational and experimental study aluminumspools with different profile configurations. Mathematical modeling product was made using ANSYS 18.2 software package. Models were verified based on actual test FP-100/1-10tn testing machine in JSC “Arconic SMZ” Central Factory Lab as per valid normative documents. trial lot spools specially developed type profile. Comparative analysis carried out against purchased previously by spool supplier.The under alloy...
