A family of inexpensive, Al2O3-forming, high-creep strength austenitic stainless steels has been developed. The alloys are based on Fe-20Ni-14Cr-2.5Al weight percent, with strengthening achieved through nanodispersions NbC. These offer the potential to substantially increase operating temperatures structural components and can be used under aggressive oxidizing conditions encountered in energy-conversion systems. Protective Al2O3 scale formation was smaller amounts aluminum than previously...
A family of creep-resistant, alumina-forming austenitic (AFA) stainless steel alloys is under development for structural use in fossil energy conversion and combustion system applications. The AFA developed to date exhibit comparable creep-rupture lives state-of-the-art advanced alloys, superior oxidation resistance the ~923 K 1173 (650 °C 900 °C) temperature range due formation a protective Al2O3 scale rather than Cr2O3 scales that form on conventional alloys. This article overviews alloy...
Abstract This case study describes how electron-beam melting, a powder bed additive manufacturing technology, helped reduce the cost and material scrap associated with production of Ti-6Al-4V brackets used in hot side engine on Lockheed Martin's Joint Strike Fighter.
