Аннотация: Method of magnetohydrodynamic treatment (MHDT) of aluminum melts was developed under the project 16-43-242013 r_ofi_m "The influence of the induced electric field on the hydrogen ions in molten aluminum alloy" with the assistance of FBM “Russian fund of basic researches”, Krasnoyarsk region government, Region state autonomous instПоказать полностьюitution “Krasnoyarsk region scientific and scientific-technical activities support fund”. Studies have shown that concentration of the alloying additives changed by the electric field which was induced in molten aluminum alloy 1417М in the direction of electric field vector. By the MHDT we can amend average value of concertation width of the ingot of the alloying elements such as cerium and lanthanum to 8 and 13 % respectively. Based on MHDT theory about movement of charged particles in induced electric field we can approve that experiment conditions (temperature 700 оС, cooling time 3 min) contribute the growth of dendrites in the direction of induced electric field vector in molten aluminum alloy 1417М. Also MHDT can reduce differences in phase composition, chemical composition and mechanical characteristics throughout the high of the ingot 1417М alloy. Furthermore approbation of new electric transfer element method in aluminum alloys which do not require the introduction of electrodes was held successfully.
