Physical Acoustics Methods for Assessing Hydrogen Embrittlement in PT-7M Grade Titanium Alloy

The effect of hydrogen concentration on the structure and physicomechanical properties of the PT-7M titanium alloy has been studied. It is established that an increase in the amount of the TiH x hydride phase leads to embrittlement of the PT-7M grade alloy, which is confirmed by a decrease in the va...

Zusammenfassung:The effect of hydrogen concentration on the structure and physicomechanical properties of the PT-7M titanium alloy has been studied. It is established that an increase in the amount of the TiH x hydride phase leads to embrittlement of the PT-7M grade alloy, which is confirmed by a decrease in the values of impact strength and an increase in microhardness. A method for a rapid ultrasonic testing of hydrogen embrittlement using bulk elastic waves has been proposed.
