The origins/mechanisms of internal friction peaks P 2 and P 3 in specimens of solid δ-hydride ZrH 1.5 , Zr–2.5Nb + 60 at.% H, Zr + 18 at.% H, etc. have been studied. Both peaks occur in a specimen of Zr + 18 at.% H, and the height of P 3 increases

International audience; Radial hydride precipitation in stress relieved Zircaloy-4 fuel claddings is studied using a new thermal–mechanical test. Two maximum temperatures for radial hydride precipitation heat treatment are studied, 350 and 450 °C

Two internal friction peaks and corresponding discontinuity (‘knee’) points of elastic modulus have been observed in hydride-forming metals upon heating and cooling, respectively. In the present work, measurements of Young’s modulus as function

Past theoretical models of delayed hydride cracking in zirconium alloys have assumed a uniform temperature distribution in the material. However, in real components, a temperature gradient may be set up, for example, when a through-wall crack leaks h

The hydride precipitate fracture strength as a function of precipitate size and temperature (23–250°C) in smooth tensile specimens of Zr–2.5Nb pressure tube material (nominal hydrogen content 100 ppm by weight) was studied using the acoustic emi

In modern CANDU nuclear generating stations, pressure tubes of cold-worked Zr-2.5Nb material are used in the reactor core to contain the fuel bundles and the heavy water (D2O) coolant. The pressure tubes operate at an internal pressure of ∼10 MPa a

Specimens of Excel alloy were charged to different hydrogen concentration levels from the gas phase. Two different techniques were used to determine the hydride dissolution and precipitation/nucleation temperatures on heatup and cooldown of the speci

A proportionality between Young's modulus and the hydrogen concentration in solid solution of alloys of Zr has been reconfirmed. This proportionality is used to monitor the increase in hydrogen content during isothermal hydrogen charging.

The steady-state velocity model of delayed hydride cracking (DHC) in hydride-forming metals developed by Dutton and Puls has been extended to non-steady-state conditions. The development of a non-steady-state DHC model is important since it makes it

Internal friction peaks P 1 , P 2 and P 3 were determined by the composite oscillator technique (APUCOT) at 40 and 120 kHz in unalloyed Zr + H and in Zr-2.5Nb + H. The effect on the peaks of hydrogen content, thermal cycling and ageing was investigat
