FIELD: metallurgy.
SUBSTANCE: light alloys ultrasonic wave velocity is measured depending on content of hydrogen in them, which differs by the fact that metal surface is provided with an acoustic emission source and a receiver; ultrasonic wave velocity is measured depending on angular position of the source and the receiver; distance between the emission receiver and sensor is measured; and at every measurement of distance and angle there determined is maximum ultrasonic wave velocity corresponding to certain content of hydrogen in metal, and as per reference relationship of ultrasonic wave velocity the hydrogen concentration corresponding to hydrogen embrittlement of light alloy is determined depending on concentration of hydrogen in metal.
EFFECT: improving accuracy of identification of hydrogen embrittlement of light titanium-base alloys.
