Abstract
beta-Ti alloy Gum metals were defined as Ti-24(Nb + Ta + V)-(Zr,Hf)-O (at.%) by Saito et al. [T. Saito et al., Science 300 (2003) 464]. Previous work has focused on compositions near Ti-23Nb-0.7Ta-2Zr-O. Here, Ti-24V-28Zr-2O was examined; similar single-crystal elastic constants were observed. However, the alloy was found to be brittle and did not form alpha '' during loading, unlike the Ti-Nb alloy. V-rich body-centred cubic precipitates were also observed. Therefore the beta stability parameters e/a, Bo and Md alone are insufficient to define the compositional range of Gum metals. (C) 2009 Acta Materialia Inc. Published by Elsevier Ltd.
