Abstract Scope Titanium alloys offer severe challenges in the application of bending as a quick throughput creep test. In the absence of steady state and with high stress levels that make elastic strains comparable to creep strains, many of the approximations that have allowed conventional, high temperature, low stress creep tests to be accelerated through the use of digital image correlation coupled to the varying stress levels in a beam, are not valid. In addition, the presence of large textured regions (MTRs), the anisotropy of slip (more difficult when stressed along <0001>) and the asymmetry of c+a slip (tension being softer than compression) complicate matters even further. This presentation will describe our present ability to identify such situations through the shift in the neutral axis of the beam and some promising methods to extract useful constitutive laws for creep from experiments on a highly textured Ti-6Al and from Ti-6Al-4V containing large MTRs.
