Effect of deuterium content on fracture toughness of Zr-2.5Nb pressure tube material in the temperature range of ambient to 300 °C
TL;DR: In this article, the axial fracture toughness of cold worked and stress relieved Zr-2.5Nb pressure tube material containing deuterium between 5 and 200wppm was determined as per ASTM E−1820-15 between 25 and 300 ÂC using 17mm wide Curved Compact Tension samples.

Investigation of hydrogen diffusivity in Zr-2.5%Nb alloy pressure tube material using Metallography and Neutron Radiography
S.K. Shukla,S.K. Shukla,Prashant Singh,Tushar Roy,Yogesh Kashyap,Yogesh Kashyap,Mayank Shukla,Mayank Shukla,Ripandeep Singh,Ripandeep Singh +9 more
TL;DR: In this paper, the absolute hydrogen content for radiography and hydride area fraction for metallography; vs distance data were fitted with error function to obtain diffusivities at various temperatures and diffusivity data were further processed to obtain the temperaturedependent diffusion coefficients for both techniques in the temperature range of 523 K-723 K.
