Abstract Scope |
This study investigates the effects of sintering temperature (1200, 1400, 1600 °C) and time (2, 4 hours) on the microstructure and mechanical properties of silicon carbide–aluminum (SiC-Al) composites produced by binder jetting 3D printing and infiltration. SiC preforms were printed, sintered under different conditions, and subjected to spontaneous aluminum infiltration in an inert atmosphere. Characterization was performed on printed (green) SiC preforms, sintered preforms, and SiC–Al composites. Phase identification and elemental analysis were conducted using X-ray diffraction (XRD) and energy-dispersive X-ray spectroscopy (EDS), respectively. The microstructure of the samples was studied via scanning electron microscopy (SEM). The stress-strain behavior of the samples was revealed by compressive tests. This work is the first to systematically explore the influence of sintering parameters on SiC–Al composites produced by binder jetting 3D printing and infiltration. The findings offer a new pathway for manufacturing high-performance composites for various applications including the aerospace and automotive industry. |
