A study of the impact of service factors on Ti-6Al-4V alloy hydrogenation at temperatures close to climatic is performed on the example of a failed hydrogen compressor. It is established that under high gas pressure conditions and possible metal heating hydrogen saturation of Ti-6Al-4V alloy can reach significant values that surpass those acceptable by one to two orders of magnitude. Hydride phases are determined in the alloy by X-ray phase analysis. Temperature programmed desorption provides identification of phase transitions occurring during hydrogen evolution from the metal.
