  • Forecasting of mechanical properties distribution by volume of articles, obtained by the method of hot deformation with the use of CAE-systems
    Prediction of distribution of mechanical properties on the volume of the products received by methods of hot deformation with use of CAE-systems. In this work the technique of research of influence of parameters of deformation process on distribution of mechanical properties of products of aluminum alloys is presented. Functional dependences of mechanical characteristics on intensity of deformation, temperature and speed of cooling are received. The software application for SAE-systems which allows to predict mechanical properties of products from aluminum alloys is created.
    Keywords: aluminum alloys, mechanical properties, prediction, СAE-system.

  • SCANDIUM: PRODUCTION AND APPLICATION
    A promising feedstock for the obtaining of scandium is alumina production sludge, in which more than 150 tons of this scattered metal are annually wasted at each Ural plant. A method of carbonization of the sludge pulp by kiln gas of alumina production is described briefly. It leads to concentration of scandium, titanium, and zirconium, and decreases the toxicity of alkaline pulp in sludge fields by converting alkali into soda-hydrocarbonates with pH value lowering from 12 down to <8,5. This technology provides the production of hundred times more rich solutions than pregnant solutions of uranium in-situ leaching. An economically effective precipitation method for recovery of scandium oxide suitable for the production of master alloys, alloys, and compounds has been proposed. An injection method of synthesis of aluminum-scandium master alloys has been developed and tested in the industrial furnaces at the KUMP Public Limited Company. Advantages of application of scandium-containing all
    Keywords: scandium, recovery, red mud, alloys, Al–Sc master alloy, scandium compounds, application.
