<p>An iron-aluminum ferritic alloy characterized by high-temperature strength, resulting from the precipitation of a fine TiSi intermetallic type precipitate of high thermal stability, and high-temperature oxidation-resistance under conditions of cyclic heating at temperatures up to about 2,500 DEG F. said alloy consists essentially of, by weight, up to about 0.1% carbon, from about 4.0 to about 8.2% aluminum, about 0.2 to 4.0% silicon, about 0.05 to 2.0% titanium, with a preferred silicon/titanium ratio between about 1.0 to 4.0, and the balance iron, incidental impurities and additions which do not materially affect the attainment of the desired properties.</p> |
