Experimental verification of the procedure of reconstructing the boundary condition in the problem of binary alloy solidification

In this paper we present the results of experimental verification of the algorithm used for solving the inverse problem consisted in determination of the heat transfer coefficient in the binary alloy solidification process when the measurements of temperature in the selected points of the cast are known. In considered model the distribution of temperature is described by means of the Stefan problem with the varying temperature at the beginning of solidification process depending on concentration of the alloy component, whereas for description of the concentration the Scheil model is applied. Experimental data were obtained during the solidification of Al-Cu alloy.
