Aluminum alloys strengthened with coherent (L1<sub>2</sub>), nanosize Al<sub>3</sub>Sc precipitates may be used as structural materials at elevated temperatures. They are creep resistant at 300°C and exhibit a threshold stress, below which creep is not measurable. Introducing ternary alloying additions, such as rare-earth elements (RE=Y, Dy, Er), that segregate within Al<sub>3</sub>Sc...
A series of investigations was undertaken to explore the processing and properties of porous titanium with 6 wt% Al and 4 wt% vanadium (Ti-6Al-4V) and an equiatomic nickel-titanium alloy (NiTi). In this study, porous materials were created in the solid state by entrapping argon in a powder compact, and subsequently...
