| Abstract: | In this paper,micro flow behavior of aluminium alloy melt between reinforcement phases with variable geometry under the drive of externally applied infiltration pressure was described,the infiltration hydrodynamic model for squeeze pressurised infiltration was presented.The effects of pressure and melt micro flow on wetting behavior and infiltration process of the melt to the reinforcement were analysed in the light of dynamic wetting behavior between flowing melt and static substrate. |
