In this paper, B-Ni-Al shield materials were fabricated by vacuum metal infiltration. The B-Ni-Al Composite were fabricated by preheating BN+Ni at 1550°C for one hour before infiltrating Al alloys into the preforms in a vacuum at 1100°C for two hours. Microstructural characterization of the materials obtained was performed using X-ray diffraction, scanning electron microscopy(SEM). Mechanical properties were evaluated by fracture toughness and bending strength. AlN was produced with interfacial reactions between Al and BN.
