    Abstract: A method of producing an FeCrAl material by gas atomization, and a high temperature material produced by the method. In addition to containing iron (Fe), chromium (Cr), and aluminium (Al) the material also contains minor fractions of one or more of the materials molybdenum (Mo), hafnium (Hf), zirconium (Zr), yttrium (Y), nitrogen (N), carbon (C) and oxygen (O). The smelt to be atomized contains 0.05-0.50 percent by weight tantalum (Ta) and less than 0.10 percent by weight titanium (Ti). Nitrogen gas (N2) is used as an atomizing gas, to which an amount of oxygen gas (O2) is added, the amount of oxygen gas being such as to cause the atomized powder to contain 0.02-0.10 percent by weight oxygen (O) and 0.01-0.06 percent by weight nitrogen (N).

    Abstract: A die (20) comprises metal-rich sections (40a, 40b) which form an inner wall and an outer wall of the die (20), respectively. Gradient sections (42a, 42b) are disposed adjacent to the metal-rich sections (40a, 40b), respectively. Further, a ceramics-rich section (44) is disposed between the gradient sections (42a, 42b). A punch (30) comprises an inner ceramics-rich section (46), a gradient section (50), and an outer metal-rich section (48). In the die (20), the composition ratio of metal gradually decreases from the metal-rich sections (40a, 40b) to the ceramics-rich section (44). Similarly, in the punch (30), the composition ratio of the metal gradually decreases from the metal-rich section (48) to the ceramics-rich section (46).

    Abstract: A compact is obtained from a mixed powder of a multi-component system ceramics composed of constitutive elements of at least two metal elements selected from the group consisting of Ti, Al, V, Nb, Zr, Hf, Mo, Ta, Cr, and W, N, and optionally C; and Fe, Ni, Co, or an alloy composed of a constitutive element of at least one metal element of Fe, Ni, and Co. A composite material is prepared by sintering the compact.
