| Abstract |
In the present study, Al-SiC_p FGMs containing 10 layers with different volume fraction of Al and SiC_p, and different geometry in thickness (3 ㎜, 5 ㎜ and 7 ㎜) were fabricated by employing the pressureless infiltration technique. Optimum condition was established to obtain the enough strength of preforms by controlling the forming pressure and binder added. Al-10%Mg was properly infiltrated into the preforms at 920℃ with N₂ atmosphere within a tube furnace. Analysis of microstructure and mechanical properties revealed that Al-SiC_p FGMs were fabricated successfully. Curvature of Al-SiC_p FGMs plates was measured to predict the internal stress distribution via a theoretical model for the analysis of thermo-mechanical deformation. |
