Abstract:
The numerical simulations of the casting process for making metal matrix composite by infiltrating melting alloys into a fiber preform arestudied. The evaluation of the infiltration flow, the thermal conduction, the stress and strains of the matrix are studied with finite element method, and the corresponding finite element program for axi-symmetry condition is programmed. The influences of the controllable initial and boundary conditions on the casting process, residual stress and residual plastic strains, and selection of optimal technological parameters are researched. The reliability of the numerical simulation is analyzed by comparison between the calculated results andsimilar experimental data.[WT5HZ]
