Improving the Fracture Toughness of Boron Carbide via Minor Additions of SiC and TiB2 Through Hot-Press Sintering

Boron carbide (B4C) is an essential material in various high-performance applications due to its light weight and hardness. In this work, B4C-based composites were fabricated via a powder route consisting of powder mixing, precursor preparation, and hot-pressing under vacuum. The composites’ mechani...
