Abstract
The influence of the lamellar orientation with respect to the loading axis on the creep behavior of Ti-48A1 PST crystals was investigated. The results indicated that the creep behavior of PST crystals is strongly dependent on the angle between lamellar boundary and loading axis, and the PST crystals yield high stress exponents for power law creep under the test conditions, which may be associated with lamellar interface and their fine spacing; at 800°C and the 350 MPa stress level, the onset of tertiary creep regime is earlier in the sample with φ = 90° compared with that in the sample with φ = 0°, which may be caused by spheriodization during creep.
