Abstract

Al-B₄C composites have found more applications in aerospace and armor industries. One of the demanded methods in manufacturing these composites is Vortex casting. In this research, a casting system was designed for manufacturing Al- B₄C composites with 5, 10, and 15 vol. %B₄C at 750, 850, and 950°C. The resulting composites were tested for their mechanical properties and microstructure to study the effect of volume fraction of B₄C and temperature parameters. It is observed that the mechanical properties enhance with increasing of particles fraction. The density of composites is affected by casting temperature. X-ray diffraction studies also confirmed the existence of boron carbide in composite samples. Additionally, according to SEM images, the distribution of B₄C particles in the matrix was found to be almost uniform.
