Young's modulus and internal friction of the V-4Ti-4Cr alloy with different hydrogen content were studied in the temperature range of 100 − 300 К at oscillation frequencies of about 100 kHz. It is shown that hydrogenation of the alloy gives rise to a minimum in the temperature dependence of Young's modulus due to the precipitation/dissolution of vanadium monohydride particles, and a relaxation peak in the temperature spectrum of internal friction at temperatures of about 140 К, which can be associated with the Snoek-type hydrogen relaxation caused by the Ti-H interaction.
