Nb–24Ti–18Si–2Al–2Hf–4Cr and Nb–24Ti–18Si–2Al–2Hf–8Cr alloys were prepared by arc melting in a water-cooled crucible under argon atmosphere. Microstructural characteristics and oxidation resistance of the alloys at 1250 °C were investigated. The results show that, when the Cr content is 4 at%, the microstructures consist of (Nb,Ti)SS and Nb5Si3; as Cr content increases to 8 at%, C14 Laves phase Cr...
The microstructures and grain boundary morphologies of a novel Co–9Al–9W–2Ta–0.02B alloy doped with yttrium (Y) (0.01, 0.05, 0.10, and 0.20; at%) were investigated as functions of aging temperatures (900 and 1000 °C) and time (50 and 150 h). The aged alloys all exhibit a γ/γ′-Co3(Al, W) coherent microstructure in grain interiors, whereas an intermetallic κ-Co3(W) phase precipitates at grain boundaries...
