Development of Low-cost, High-strength Hot-corrosion-resistant Iron Aluminum-base Alloys.
NTIS: PB 259 253 Available for Reference At Bureau Libraries :94 pages
This report describes attempts to prepare fe-al-mo alloys with sufficient high-temperature strength to be competitive with stainless steels for oxidizing and/or hot-corrosive environments and to provide competitive alternatives to superalloys based on domestically produced alloying elements. An 8 percent aluminum, alloy, which exhibited good room-temperature ductility, had superior strength at 815 deg c and oxidation resistance equivalent to type 321 stainless steel. High aluminum (12 to 15 percent) alloys showed outstanding oxidation resistance as high as 1,370 deg c, but need more study to improve thermomechanical processing and strength.
