Abstract：In this paper, “ casting-hot rolling ” method was used to simulate “ continuous casting-hot rolling ” for preparing
Al/(Al-B 4 C)/Al laminated composite material; the microstructure and properties of the prepared composite samples were
analyzed. The results show that Al particles and Al-B 4 C particles are uniformly distributed on the cross section; and there
are no agglomeration phenomena of Al-B 4 C particles, these results prove that the experimental method is feasible. The clad
ratio of laminated composite plate with different thickness after rolling was calculated, and the Vickers hardness was
measured. The results show that the properties of Al/(Al-B 4 C)/Al laminated composite are excellent. When the overall
thickness of the sample is 3 mm, the clad ratio is the highest, and the hardness value at the center of the central layer is the
highest. These provide a reference for follow-up research.
