    摘要: A method of producing a ceramic matrix composite is provided, which production method reduces metal residual percentage within matrix with little energy consumption, without requiring special external heating means and special equipment while it is industrially simple and at a low price. It is a method of producing a ceramic matrix composite having the steps of filling mixed powder obtained by mixing metal powder and boron nitride powder into a predetermined container to form a green compact having a porous structure, and infiltrating the above described green compact with molten Al to form a composite material containing metal boride and having aluminum nitride as a matrix. The green compact is formed by compressing the mixed powder whose mixing ratio of metal powder to boron nitride powder is 1:1.8 to 1:2.2 (molar ratio) so that porosity of the green compact is 34 to 42%.

    摘要: A method and corresponding device for compacting a powder material into a homogenous article. The method includes the steps of, placing the powder material in a molding cavity connected to a gas source, blowing gas into the lower end of the molding cavity so that the particles in the powder material are suspended in a gas stream, sealing the upper end of the molding cavity by an upper pressing punch, connecting the lower end of the molding cavity to a vacuum source, sealing the connection to the vacuum source by moving a lower punch relative to the lower end portion of the molding cavity, and thereafter compacting the powder material with the help of the pressing punch. The apparatus for performing the method includes a molding cavity having sidewalls, an upper and lower punch moveable within the molding cavity an opining in communication with the molding cavity for blowing gas into, and sucking gas out of the cavity, wherein the lower punch is moveable between a first position in which an upper end surface of the punch is located below the opening, to a second position in which the opening is covered by a sidewall of the lower punch.

    摘要: This invention relates to a method of manufacturing an improved ferritic or martensitic alloy based on iron and chromium strengthened by a dispersion of oxides, commonly called an Oxide Dispersion Strengthened or ODS alloy, and, more particularly to a method of manufacturing a ferritic or martensitic ODS alloy with large grains based on iron and chromium which has a single phase ferritic or martensitic matrix having an isotropic microstructure and a grain size that is sufficient to guarantee mechanical strength compatible with a use of this alloy at high temperature and/or under neutron irradiation. According to the invention, the method comprises slow cooling of an austenite at a cooling rate less than or equal to the critical cooling rate for transformation of this austenite into ferrite.
