The high hardness combined with its lower density makes boron carbide an attractive candidate for armour material. The ballistic performance of hot pressed boron carbide tiles were evaluated using standard Depth of Penetration (DOP) test method against hard steel armour piercing (AP) projectile of 12.7 mm caliber. Aluminium alloy 2024-T351 was used as backing material. The effect of tile thickness...
The present investigation has been made on the influence of temperature on the workability behavior, stresses and hardness of sintered Al-4%B4C at a strain rate of 0.1s-1 during upsetting. Al-4% B4C preforms were prepared with 90% of initial preform density and sintered at 550±10oC about 60min. These sintered preforms were compressed in a hydraulic press at a strain rate of 0.1 s-1 until the initiation...
