Abstract
Influence of a slowly rotating 0.5Â T transverse magnetic field on the directionally solidified metallic alloy has been experimentally studied in this work. Main idea is to study an influence on the melt flow and material structure caused by the simultaneous electromagnetic stirring and thermoelectromagnetic convection with comparable magnitudes. Electromagnetic stirring and thermoelectromagnetic convection intensities have been estimated analytically to find optimal experimental parameters. It is experimentally demonstrated that with such an interaction it is possible to modify component macrosegregation of Sn-10Â wt% Pb alloy. Helical macrosegregation within cylindrical sample is obtained as a result of simultaneous influence of thermoelectromagnetic convection (TEMC) and electromagnetic stirring of the liquid melt. Obtained experimental results allow to determine TEMC velocity by comparing the intensities of TEMC and electromagnetic stirring.
