Influence of temperature on threshold stress for reorientation of hydrides and residual stress variation across thickness of Zr-2.5Nb alloy pressure tube
TL;DR: In this paper, the threshold stress, σth, for reorientation of hydrides in cold worked and stress-relieved (CWSR) Zr 2.5Nb pressure tube material was determined in the temperature range of 523-673 K.
Journal ArticleDOI
Delayed hydride cracking in Zr–2.5Nb pressure tube material: influence of fabrication routes
TL;DR: In this article, the delayed hydride cracking (DHC) velocity was measured for Zr-2.5Nb alloy pressure tubes manufactured from cold-worked and stress-relieved (CWSR) route and quenched and aged (Q&A) route at 162, 203, and 250
Journal ArticleDOI
Influence of hydrogen content on fracture toughness of CWSR Zr-2.5Nb pressure tube alloy
TL;DR: In this paper, the fracture toughness of unirradiated, cold worked and stress relieved (CWSR) Zr-2.5Nb pressure tube alloys used in Indian Pressurized Heavy Water Reactor is reported.
Journal ArticleDOI
Effect of radial hydride fraction on fracture toughness of CWSR Zr-2.5%Nb pressure tube material between ambient and 300 °C temperatures
TL;DR: In this article, a curved Compact Tension specimens of 17"mm width containing 100 wppm of hydrogen were made using electro discharge machining, and they were subjected to gaseous hydrogen charging and stress reorientation treatment to form radial hydrides.
Journal ArticleDOI
Investigation of elevated-temperature mechanical properties of δ-hydride precipitate in Zircaloy-4 fuel cladding tubes using nanoindentation
TL;DR: In this paper, the authors measured Young's modulus and hardness for metal matrix of Zircaloy-4 cladding and δ-hydride embedded within its matrix using nanoindentation for the temperature range of 300 k −773 k.
