摘要：A method of producing an FeCrAl material by gas atomization, and a hightemperature material produced by the method. In addition to containing iron (Fe),chromium (Cr), and aluminium (Al) the material also contains minor fractions of one ormore of the materials molybdenum (Mo), hafnium (Hf), zirconium (Zr), yttrium (Y),nitrogen (N), carbon (C) and oxygen (O). The smelt to be atomized contains 0.05-0.50percent by weight tantalum (Ta) and less than 0.10 percent by weight titanium (Ti).Nitrogen gas (N) is used as an atomizing gas, to which an amount of oxygen gas (O) isadded, the amount of oxygen gas being such as to cause the atomized powder to contain0.02-0.10 percent by weight oxygen (O) and 0.01-0.06 percent by weight nitrogen (N).
