The properties of particle reinforced composites are often limited due to the interface between reinforcements and matrix materials. In this study, double-layer structure 2024Al-2024Al/B4C composites were fabricated by plasma activated sintering (PAS) under the condition of 530°C, 3 min, 20 MPa. Effect of B4C content on the mechanical behavior of the composites was investigated. When the B4C content in the higher layer is 17.5 wt.%, the bending strength of the composite is 1099.68 MPa. In addition, the hardness of the substrate surface is 136.58 HV, and the composite surface is 198.68 HV. This kind of material introduces the design idea of the function gradient material and the microstructure control, which makes the effective transition of the interface between the reinforcements and matrix materials, meeting the special need of works.
