Multiscale model of segregation process

Abstract: The microsegregation process proceeding in the single grain volume is analyzed. The distribution of alloy component in the domain considered is described by the broken line (boundary layer and the remaining part of liquid subdomain). The temporary solidification rate of grain results from the macro model of thermal processes proceeding in the casting domain (the temperature in the casting volume is assumed to be equalized and only time-dependent). In the final part of the paper the example of computations is shown
