| Abstract Scope |
Dwell fatigue in titanium alloys at room temperature is influenced by static creep during holds at peak stress in fatigue cycle and is also known to vary with temperature. We have therefore studied the effect of texture and composition on creep of alpha titanium in Grade 1, Grade 4, and Ti-6wt%Al alloys heat treated to a common grain size. Strong texture and composition effects are seen on compression creep at room temperature. Tensile creep has also been studied from room temperature to 200C in the Ti-6wt%Al alloy. Dynamic strain aging effects are seen throughout this temperature range. Activation energies and activation volumes are measured to deduce the macroscopic mechanism of creep. This study is supported by analysis of plasticity with DIC, surface slip offsets and TEM, together with crystal plasticity analysis to understand the effects of elastic and plastic anisotropy on creep. |
