Metallic composites exhibiting tailorable mechanical and thermal properties as well as good damage tolerance have applications in aerospace, and automotive industries, among others. Binder jet 3D printing (BJ3DP) can be used to effectively manufacture complex shapes with high resolutions. In this research, BJ3D printed samples of designed structures with lattice sizes within few millimeters are printed using steel powders such as 316L and HSLA (high-strength low-alloy) steel. To further improve the strength of the alloys, design strategies were applied through matrix strengthening by oxidation dispersion, alloy infiltration, and geometry design, aiming the ultra-high mechanical performance than traditional steel components. The sintering and infiltration procedure are guided through the CALPHAD (Calculation of Phase Diagrams) approach and are further optimized experimentally. The tensile and toughness of different builds are evaluated to identify the best design pathways of metallic composites.
