Abstract
A method of manufacturing high-temperature-resistant shaped parts of an iron-chromium-aluminum alloy containing 2-10 wt % aluminum, 10-40 wt % chromium, and the balance basically iron is provided. According to this method, the composition in powdered form is hot isostatically pressed to a predetermined shape to form a product. Optionally, the product may be pre-oxidized to form a protective layer of aluminum oxide on a surface thereof.
