Effects of Creep in Titanium at Room Temperature during Tensile and Profilometry‐Based Indentation Plastometry Testing

This work concerns the mechanical response of three Ti‐based alloys at room temperature, which is observed to be “creep‐affected” and hence to exhibit a dependence on time (within the “quasi‐static” range of strain rate). They have been tensile tested (over this range of strain rate) and subjected to profilometry‐based indentation plastometry (PIP) with a range of penetration velocities (and hence of effective average strain rate). In addition, they have been creep tested, with different fixed loads (corresponding to nominal stresses in the vicinity of the yield stress). Using the Miller–Norton equation to capture creep strain histories, the outcomes of these tests have been converted so that they correspond to those expected with a fixed true stress. These characteristics have then been used in a simple numerical model of a tensile test, incorporating the effect of creep. Good overall consistency is observed and the procedures described here are thought to have wide potential for the extraction of both plasticity and creep characteristics from a simple series of tensile (or PIP) tests carried out with a range of strain rates.
