Abstract
Data are reported on the elastic constants and ultrasonic attenuation of a single crystal of Nb determined as a function of the hydrogen content (0 ≤ H/Nb ≤ 0.71) at 528 K and as a function of temperature (380 [MATH] ≤ 528 [MATH]) for H/Nb = 0.31, 0.45, 0.53 and 0.71. A relaxation process is observed which appears to be a Zener-type of effect.
