The invention relates to a method for improving the mechanical properties of an amorphous endogenous composite material through recovery of an amorphous matrix structure, and belongs to the field of amorphous alloys and endogenous composite materials. The microstructure characteristics of this kind of amorphous endogenous composite material are: the endogenous crystalline phase with reversible phase transition is distributed in the amorphous matrix. Under tensile loading, such amorphous endogenous composites exhibit superelasticity, i.e. complete shape recovery after small strain unloading. Through tensile cyclic loading at small strains, the amorphous matrix phase in the amorphous endogenous composites undergoes structural recovery driven by the "shape memory effect". The structurally restored amorphous matrix can lead to a significant improvement in the mechanical properties of amorphous endogenous composites, including improved tensile plasticity and prolonged work-hardening stages. This method can improve the mechanical properties of the amorphous endogenous composite material, and then expand its practical application as a structural material, which has important social and economic benefits.
