    Abstract: PURPOSE:To provide a fiber-reinforced metal which has overall excellent mechanical characteristics by consisting the same of continuous inorg. fibers consisting of Si, Ti or Zr, C and O and an Al alloy base material contg. a prescribed ratio of Ni and incorporating the needle-like phase of said alloy into said Al base material. CONSTITUTION:The continuous inorg. fibers which consist of an amorphous material substantially composed of Si, M, C and O, or solid soln. such as beta-SiC, MC (M is Ti or Zr) and/or respective ultrafine crystalline particles and aggregate, etc., consisting of amorphous SiO2 and MO2 and consist of Si, Ti, or Zr, C and O are prepd. Such continuous inorg. fibers and the Al alloy member contg. 0.5-6wt% Ni are combined by a casting method, more particularly high-pressure casting method and are solidified in a short period. The combined material is cooled from the direction orthogonal with the continuous fibers in the stage of such solidification, by which the fine needle-like crystalline material is crystallized in entanglement with said fibers in the direction perpendicular to the fibers among the continuous fibers, by which the excellent inter- layer shearing strength is imparted. As a result, the fiber-reinforced metal (FRM) having high strength is obtd.

    Abstract: PROBLEM TO BE SOLVED: To provide a ceramic having a surface layer with a gradient composition, which has excellent functions such as photocatalytic functions, electrical functions, thermo-catalytic functions or a function as a catalyst carrier, or environmental resistance such as oxidation resistance, alkali resistance or wear resistance, and excellent mechanical properties, and to provide a method of producing the same. SOLUTION: The ceramic comprises a composite phase which is constituted of a first phase mainly comprising silicon-based ceramic components and a second phase mainly comprising ceramic components other than the ceramic components in the first phase, and the present ratio of fine crystalline particles of at least one kind of the ceramic components constituting the second phase is increased in a gradient manner toward the surface layer.

    Abstract: PROBLEM TO BE SOLVED: To provide a fastening structure element for high-temperature structure body by setting the content of inorganic fiber to a specific value and allowing a layer an amorphous and/or crystalline carbon of a specific thickness to distribute as boundary layers between the inorganic fibers and the inorganic substance and between the fibers. SOLUTION: Inorganic fibers are included in the inorganic fiber-bonding type ceramic composite in an amount of >=80 vol.%. On the surfaces of individual inorganic fibers, amorphous and/or crystalline carbon is formed in an incommensurate phase as a boundary layer in an thickness of 1-200 nm and the inorganic substance distributes so that the gaps of the inorganic fibers may be filled with the inorganic substance. Thus, the developed crack can be deflected even in the inside part of the boundary layer, and the fracture resistance of this ceramic is markedly increased. This characteristics can become a merit for a screw structure part as a binding structure element for the assembly part, in other words, the production of bolts and nuts.
