In this study, SIMMER-III is extended to simulate the eutectic reaction between stainless steel and B4C. On the basis of experimental results, growth of the eutectic material is modeled by the parabolic rate law. Heat and mass transfer processes are also modeled. A test calculation is conducted to validate the developed eutectic reaction model.
