The Study of Hydrogen Accumulation Dynamics in Ti-6Al-4V Nanocrystalline Alloy

Abstract:

This work presents the results of hydrogen diffusion study in macro-and nanocrystalline titanium using the method of combining an electrolytic cell with vacuum chamber through the membrane. It has been stated that the formation of nanocrystalline structure, on the one hand, leads to the decrease in the effective hydrogen diffusion coefficient and, on the other hand, to the increase in the capability to accumulate hydrogen. This is observed due to more developed grain boundaries in nanocrystalline samples as compared with macrocrystalline.
