| الوصف: | The corrosion-fatigue strength in 3% aqueous NaCl solution and the resistance against hot salt corrosion (HSC) of the fine-grained near-a alloy Ti-5Al-2V (Russian analog of Grade 9 titanium alloy with increased aluminum content) has been studied. The properties of the Ti-5Al-2V alloy in the coarse-grained state, in the fine-grained after cold Rotary Swaging (RS), in partly recrystallized state, and in fully recrystallized one have been investigated. The mechanical properties of the alloy were characterized using compression tests and microhardness measurements. The effects of RS and of the annealing temperature and time on the character of corrosion destruction of the surface and on the composition of the products of the HSC were studied. RS was shown to result in an increase in the depth of the intergranular corrosion defects while the recrystallization annealing promotes the increasing of the corrosion resistance of the Ti-5Al-2V titanium alloy. The parameters of the Basquin equation for the corrosion-fatigue curves for the near-a Ti-5Al-2V alloy in the coarse-grained state, in the severely strained one, and after recrystallization annealing were determined for the first time. An effect of nonmonotonous dependencies of the slopes of the corrosion-fatigue curves for the strained near-a Ti-5Al-2V alloy on the recrystallization annealing temperature has been observed.
