UL TRASOUNDS INFLUENCE ON THE ELECTRICAL CONDUCTIVITY OF LIQUID ALUMINIUM

摘要

We present the results of the experimental measurements concerning the electrical conductivity of liquid aluminium between 661-770deg C and the way in which the values of this physical quantity varies under the action of ultrasounds in the mass of the liquid metal. The differences which occur between the values of the electrical conductivity in the two cases (with and without the action of ultrasounds) are discussed on basis of the specific processes induced by the action of the ultrasounds in the mass of the liquid metal.
