摘要：

Reaction-bonded boron carbide was manufactured by infiltrating porous boron carbide preforms at 1273K with a Mg-Si eutectic alloy. The resulting composite material consists, in addition to the original B4C, of SiC, Mg2Si, and a Mg-rich complex boride/carbide Mg-x(Al,Si)(y)(B,C)(z) phase. The composites display high hardness (1700HV), Young's modulus (356MPa) and a moderate bending strength (230MPa). The ballistic efficiency (of about 6.7), as determined by the depth of penetration method, is much higher than that of alumina and similar to that of silicon-infiltrated reaction-bonded composites.
