Abstract
In this paper, Al2O3 functional gradient structures (FGS) were prepared by digital light processing-based 3D printing, and Al2O3/Al interpenetrated FGS was subsequently obtained by melt infiltrating. The microstructure of Al2O3FGS and Al2O3/Al interpenetrated FGS was studied. And the mechanical properties of Al2O3 FGS and Al2O3/Al interpenetrated FGS under quasi-static compression loading were investigated in detail. Compressive strength, Young's modulus, and energy absorption of Al2O3 FGS and Al2O3/Al interpenetrated FGS were experimental tested, compared, and discussed. The failure behavior of Al2O3 FGS and Al2O3/Al interpenetrated FGS was analyzed by experiments and FEA. This study provides a novel approach for the fabrication of ceramic FGS and ceramic/metal interpenetrated FGS with high mechanical performance.
