Abstract

In this paper, aluminum alloy matrix hybrid composite reinforced by Al18B4O33 with the addition of BaPbO3 was fabricated by squeeze casting technique. The fabrication and characterization of the hybrid composite were investigated. The result of microstructural characterization shows that BaPbO3 particles have a reaction with 6061Al alloy to produce an interfacial reaction layer which contains nanosized Pb agglomeration and Ba0.956Mg0.912Al10.088O17 compound during fabrication process. The hybrid composite has better specific strength and specific stiffness compared with conventional anti-radiation materials. Meanwhile, the theoretical calculation of mass attenuation coefficient demonstrates that the introduction of BaPbO3 particles can improve the radiation protection property of the matrix indeed. The hybrid composite has a good combination of mechanical properties and radiation protection property.
