| Abstract: | On the basis of the micro mechanics of particle/interface interaction duing solidifacation in particle reinforced metal matrix composites, a numerical model for the temperature field and the shape of solid/liquid interface near a particle ,the forces acting on the particle,as well as the critical condition for the engulfment/pushing transition has been developed. How the thermal conductivity, particle size and solidification velovity affect the partcle/interface behaviour was dissussed. |

| Keywords: | solidification interaction between partical and interface numerical model metal matrix composites |
