摘要： An efficient method for preparing a highly-directional highly-dense two-dimensional material film. The method comprises: using a circular tube with a smooth inner surface as a casting mold; and pouring a solution containing a two-dimensional material into the mold when the mold rotates at high speed in a circumferential direction, wherein the solution is uniformly coated on the inner surface of the mold by centrifugal force, the centrifugal rotation generating a shearing force that causes the two-dimensional material to be directionally and regularly arranged layer upon layer in a circumferential direction in the solution, and, the centrifugal force facilitates highly-dense accumulation of the two-dimensional material, thereby obtaining a highly-directional highly-dense two-dimensional material film. The method is applicable in the preparation of a variety of two-dimensional materials such as graphene, a composite material film thereof, and a laminated heterostructure film, and greatly improves electrical, thermal, and mechanical properties of a film.

摘要： Provided in the present application are a rare-earth microalloyed steel and a control process. The steel has a special microstructure, and the microstructure comprises a rare earth-rich nanocluster having a diameter of 1-50 nm. The nanocluster has the same crystal structure type as a matrix. The rare earth-rich nanocluster inhibits the segregation of the elements S, P and As on a grain boundary, and obviously improves the fatigue life of the steel. In addition, a rare-earth solid solution also directly affects a phase change dynamics process so that the diffusion-type phase change starting temperature in the steel changes at least to 2° C., and even changes to 40-60° C. in some kinds of steel, thereby greatly improving the mechanical properties thereof, and providing a foundation for the development of more kinds of high-performance steel.

摘要： The present invention relates to the field of MAX-phase ceramic-based composites, specifically to a short-fiber-reinforced oriented MAX-phase ceramic-based composite and a preparation method therefor. By using a new process with a fiber, a nano lamellar MAX-phase ceramic powder, other additives, etc., for preparing a fiber-reinforced MAX-phase ceramic-based composite, a novel ternary composite is prepared, wherein a matrix is composed of a highly oriented lamellar MAX-phase ceramic, the fiber is distributed parallel to the lamellar MAX-phase ceramic in an axial direction, and a granulate ceramic phase enhancement phase is dispersed in the matrix. Thus, the problems of a MAX-phase ceramic-based composite matrix material prepared by an existing method, such as coarse grains, multiple internal defects and a low strength, and a poor fracture toughness; and a reaction sintering temperature being too high such that fibers are chemically and physically damaged in a substrate, resulting in performance degradation, are solved. Fibers prepared by the method are suitable for large-scale industrial preparation and have properties that are far superior to those of any existing known fiber MAX-phase composite.

摘要： A method for improving mechanical properties by changing a gradient nanotwinned structure of metallic materials is the technical field of nanostructured metallic materials. The method uses the inherent principles of microstructure and mechanical properties of metallic materials to improve materials mechanical properties. The metallic materials has a gradient nanotwinned structure. The principles of microstructure and mechanical properties of the metallic materials mean that the mechanical properties of the metallic materials are adjusted by changing the structural gradient scale of the nanotwinned structure. The method combines two strengthening methods of nanotwins and gradient structure, and can obviously improve the mechanical properties of the metallic materials. For pure copper materials of the gradient nanotwinned structure prepared by an electrodeposition technology: the yield strength is 481±15 MPa, the tensile strength is 520±12 MPa, the uniform elongation can be 7±0.5%, and the elongation to failure can be 11.7±1.3%.
