On the Dominance of Creep–Fatigue Interaction Over Oxidation in Thermomechanical Fatigue Behavior of a Diffusion Aluminide Coated Near α Titanium Alloy
Tóm tắt
In the present study, in-phase (IP) and out-of-phase (OP) mechanical strain controlled thermomechanical fatigue tests at two strain rates, viz. 6.67 × 10–5 s−1 and 3.33 × 10–4 s−1, have been conducted on a near α titanium alloy applied with a diffusion aluminide coating. Microstructural examination of failed specimens revealed the most likely operative mechanisms causing reduction in fatigue life. While lowering the strain rate was found to cause creep–fatigue interaction in IP-TMF loading, severity of oxidation increased marginally in case of OP-TMF loading. The alloy exhibited lowest fatigue life under IP-TMF loading at 6.67 × 10–5 s−1 which was attributed to the dominance of creep–fatigue interaction over other operative mechanisms.
