The eutectic reaction phenomenon was analyzed based on the Moving Particle Semi-implicit (MPS) method. The improved MPS code was applied to three-dimensional Pb-Sn system experiments conducted at Central Research Institute of Electric Power Industry (CRIEPI). The experiments dealt with solid-solid contact materials at 225 and 205 °C. The mass diffusion process was modeled based on Fick's second law. The criterion of eutectic reaction was modeled based on binary phase diagram. The calculated penetration rates, i.e. height reduction rates, were compared with the experimental measurements. The results obtained by the MPS simulations exhibit good agreement with the experiments carried out at 205 and 225 °C. MPS simulation predicted that Sn particle will liquefy earlier than Pb particle.
