B4C is a common neutron absorbing materiahIn this paper, diffrent A1-B4C composites were manufactured by vacuum sintering, and the mierostrueture and mechanical proper6es of the composites were analyzed.The results show that the distribution of the A1 phase and the reinforeing phase B4C particles are relatively uniform. There are lower detects such as blowhole and cracks.The tensile strength, yield strength and elongation alter fracture of composites decrease with the increase of boron carbide content. The fracture modes of composites include not only the cleavage fracture of B4C particles, bu...
