However, with the progress of technology, the application scenarios of materials are diversified and complicated, and the requirements for the performance of metal materials are continuously increased, especially the strength and toughness of the materials. In the metal material, atoms are regularly arranged, but a local area has defects, and the metal is easy to break and fail at the positions of the defects under the action of external force; however, under a certain range of stress, defects in metal such as dislocation, stacking fault and the like can slip along one direction, the material has the capability of plastic deformation, the macroscopic appearance is toughness, and the strength and the toughness of the material are a pair of intrinsic contradictions: high strength requires dislocations that are not easily mobile, while toughness requires dislocations that are easily slipped. The strength and toughness of the material are thus an inverse relationship. Commonly used means of material strengthening include solid solution strengthening, fine grain strengthening, second phase strengthening, and work hardening. The solid solution strengthening, the second phase strengthening and the work hardening are all used for improving the strength on the basis of sacrificing the plasticity of the material; although the fine grain strengthening can realize the simultaneous improvement of the strength and the plasticity, the improvement is very limited, and researches on ultra-fine grains or nano-crystals find that the smaller the grain size of the material is, the more the grain boundaries are, the more difficult the plastic deformation is, when the grain size is 10-15nm, the yield strength can reach more than 10 times of that of a common coarse crystal, but the elongation is generally less than 5%. Therefore, strengthening and toughening of materials have been a hot spot in research in the field of metal materials. The calcium carbonate material has poor hardness and plasticity, but the mechanical property of the calcium carbonate material is obviously improved by utilizing the special structure of the shell, and the high toughness, the high strength, the use reliability and the like of the material can be realized through the fine design of simple composition and complex structure. According to the shell structure, a toughening concept of 'strengthening in bricks and toughening a mud net' is provided, based on heterogeneous design and forming, a gradient deformation effect is caused by response difference of different materials to stress, a failure mode of the materials is changed, and a toughening effect is achieved.
As a novel material preparation method, additive manufacturing can realize layer-by-layer channel-by-channel deposition of materials, and has important potential in the aspect of preparing high-toughness composite materials. The high-toughness composite material prepared by the additive manufacturing method can be divided into powder additive manufacturing and wire powder mixing deposition according to the feeding mode. The invention patent with the publication number of CN111451502A discloses a partition regulation and control method for in-situ synthesized TiC reinforced titanium-based composite material through additive manufacturing, which prepares a series of C/Ti composite powder with different nano-carbon contents and adopts a high-energy beam additive manufacturing method to prepare the in-situ synthesized TiC reinforced titanium-based composite material. The powder components are adjusted, the high-toughness composite material is prepared by the additive manufacturing method, the requirement on the powder is high, a large amount of powder is wasted due to the change of the material components, the additive efficiency is low, and the preparation of a large-scale component is difficult to realize.
