Embodiment 1
[0036] The highly plastic quasi-reticular titanium-based composite material in this embodiment uses CT20 titanium alloy as the matrix, and uses the in-situ self-generated TiC phase and TiC@graphene of graphene and CT20 titanium alloy matrix as reinforcements. The reinforcements are uniform and Discontinuously distributed at the original β grain boundary of the CT20 titanium alloy matrix, forming a quasi-network structure, the average diameter of the mesh in the quasi-network structure is 60 μm.
[0037] The preparation method of the highly plastic quasi-network structure titanium-based composite material of the present embodiment comprises the following steps:
[0038] Step 1. Surface pretreatment of CT20 titanium alloy powder: immerse 220 g of CT20 titanium alloy spherical powder particles in a 2M mixed acid solution for acid leaching for 15 minutes. The mixed acid solution consists of a hydrochloric acid solution with a mass concentration of 37% and a mass concentration of 40...
