The solution of the inverse problem involving the designation of the boundary condition in the problem of the binary alloy solidification for known temperature measurements at a selected point of the cast is presented. In the discussed model, the temperature distribution is described by means of the Stefan problem with varying in time temperature corresponding to the beginning of solidification and depending on the concentration of the alloy component. Whereas to describe the concentration, the Scheil model was used.

W pracy przedstawiono rozwiązanie zagadnienia odwrotnego polegającego na określeniu warunku brzegowego w zagadnieniu krzepnięcia stopu dwuskładnikowego, gdy znane są pomiary temperatury w wybranym punkcie odlewu. W rozważanym modelu rozkład temperatury opisany został zagadnieniem Stefana ze zmienną w czasie temperaturą odpowiadającą początkowi procesu krzepnięcia, zależną od stężenia składnika stopowego. Do opisu stężenia wykorzystano model Scheila.
