B4Cp/Mg-8Li-1Zn and B4Cp/Mg-8Li-1Al-1Y composites were prepared with hot-extrusion solid-state composite processing. The microstructures and mechanical properties of the composites were studied. With the optimized parameters, the deformation effects and the migration of a phase are improved, and the amount and size of foil gaps are decreased. The bonding force between foils is improved, and the oxidation of foils is lowered. The results of tensile test show that the strengths of the B4Cp/Mg-8Li- 1Zn and B4Cp/Mg-SLi-1Al-1Y composites are increased obviously after hot-extrusion solid-state composite processing (238 MPa and 257.23 MPa, respectively). The specific strength of B4Cp/Mg-8Li-1Al-1Y composite is the highest (169.23×103 cm).
