Conclusions
Improved testing procedures show that raising the solution annealing temperature appears to increase both the primary and steady-state creep resistance of Ti 6242Si. This beneficial effect may be derived from a combination of several sources, including the removal of such micrographic features as banding or texturing and especially the altering or refining of the α or β microstructure.
Small concentrations of Ni appear to segregate uniformly into the β phase and dramatically degrade the creep properties of Ti 6242Si. The explanation for this is unclear.
Small additions of Cr have little, if any, affect on the creep resistance of the alloy.
The β phase, which comprises only about 10 pct of the alloy, may have a much more important role in the creep of Ti 6242Si over the small strain range examined than previously acknowledged.
