Paper 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.
