A heterogeneous composite consisting of near-nano ceramic clusters dispersed within a ductile matrix. The composite is formed through the high temperature compaction of a starting powder consisting of a core of ceramic nanoparticles held together with metallic binder. This core is clad with a ductile metal such that when the final powder is consolidated, the ductile metal forms a tough, near-zero contiguity matrix. The material is consolidated using any means that will maintain its heterogeneous structure.

To provide a method for manufacturing a three-dimensional shaped object in which a three-dimensional shaped object is manufactured by discharging a shaping material from a discharge unit toward a stage to stack a layer, the method for manufacturing a three-dimensional shaped object includes: a first step of generating path data having a plurality of partial paths through which the discharge unit moves while discharging the shaping material; a second step of determining a line width of the shaping material in each of the partial paths and generating line width information for implementing the line width; a third step of generating shaping data including the path data and the line width information; and a fourth step of shaping the three-dimensional shaped object according to the shaping data. In the second step, the line width in a target path that is one of the partial paths is determined in accordance with a distance between a first wall and a second wall separated by the target path. The first wall and the second wall are side edges of the shaping material discharged in the partial path generated before the target path or a contour line of the three-dimensional shaped object.

A method of manufacturing an extruded material of carbon nanotube reinforced aluminum matrix composite having improved corrosion resistance, and the extruded material manufactured thereby are proposed. The method may include manufacturing an extruded material comprising an aluminum-carbon nanotube composite material and forming a hard oxide film on the surface of the extruded material by anodizing the extruded material in a mixed solution of sulfuric acid and oxalic acid. The method can form a hard oxide film with excellent corrosion resistance, abrasion resistance, and insulation properties on the surface of a composite material (an extruded material of carbon nanotube reinforced aluminum matrix composite material), which is known to be difficult to conduct hard anodizing due to the difference in corrosion characteristics between materials and, accordingly, the usability of the composite material can be significantly improved.
