To address the strength-toughness dilemma, ceramic/metal interpenetrating phase composites (IPCs), fabricated through metal infiltration into ceramic perform, have been investigated. However, infiltrating metal into porous ceramic scaffold with high volume fraction remains a significant challenge. Herein, we propose a novel method to fabricate highly dense AlO/AlSi10Mg (Al) interpenetrating phase composites through ultrasonic-assisted pressureless infiltration into 3D printed ceramic scaffolds. Experimental results indicate that the as-fabricated AlO/Al IPCs exhibit excellent quasi-static and dynamic mechanical properties. Specifically, the materials can achieve high specific compressive strengths of 148.6 ± 5.2 MPa/(g/cm) under quasi-static compression and 228.6 ± 4.5 MPa/(g/cm) under dynamic compression while also exhibiting high specific energy absorption of 33.6 ± 0.9 J/g under quasi-static compression and 37.7 ± 1.1 J/g under dynamic compression. The specific compressive strength and specific energy absorption of the as-fabricated AlO/Al IPCs outperform those of the literature-reported ceramic/metal IPCs. This work provides an innovative approach to fabricate strong and tough ceramic composites.
