The zirconium alloys used in nuclear industry include mainly Zr–Sn and Zr–Nb alloys of
different chemical composition, microstructure and susceptibility to both hydrogen …

Hydrogen moves in zirconium because of forces associated with gradients in concentration
and stress. When solubility limits are reached, stable hydrides form within control volumes …

Abstract The Zr–2.5 Nb alloy is used as pressure tubes in Canadian Deuterium Uranium
(CANDU) nuclear reactors, and the typical starting microstructure consists of α-Zr grains …

The equiatomic CoCrNi medium entropy alloy (MEA) has shown better mechanical
properties than many MEAs and high entropy alloys (HEAs) at room temperatures. However …

Delayed hydride cracking (DHC) is a potential failure mechanism of Zr-2.5 Nb alloy pressure
tubes, employed in heavy-water reactors. This study focused on understanding the DHC …

The microstructural evolution and mechanical properties of a duplex Zr-2.5 Nb alloy
annealed at different temperatures have been studied in detail. The results show that after …

Cantilever beam samples with V-notches were employed to measure the radial delayed
hydride cracking rate (DHCR) in Zr-2.5 Nb alloy pressure tubes within the temperature range …

The effect of heavy ion or neutron irradiation on the plasticity of Zr-2.5 Nb pressure tube alloy
is investigated by a combination of nanoindentation and numerical modeling, with …

The susceptibility of delayed hydride cracking (DHC) in the Zr-2.5% Nb alloy was evaluated
in six microstructures produced from an extruded tube of Zr-2.5% Nb, which underwent …

The delayed hydride cracking (DHC) velocity was measured for Zr–2.5 Nb alloy pressure
tubes manufactured from cold-worked and stress-relieved (CWSR) route and quenched and …
