An ultrasonic method has been developed to observe the solid solubility phase transition of metallic hydride in zirconium-niobium alloy. This measured the change in ultrasonic velocity with temperature as the sample was cooled through the expected solid solubility temperature (SST). At the SST, free hydrogen forms a hydride precipitate within the metallic structure on cooling, and the temperature dependence of ultrasonic velocity was seen to change at this temperature, for both longitudinal and shear waves. These results were compared to those of thermal expansion, using a dilatometer, where again the SST could be estimated. Analysis of the data indicates that both measurements could be used as the basis for a possible nondestructive estimation of hydrogen content in these alloys. (C) 1997 Elsevier Science B.V.
