The effect of radial hydride on the room temperature fracture toughness of the Zr-2.5 Nb
pressure tube material with 100% radial hydrides and hydrogen content up to 320wppm was …

Axial fracture toughness of cold worked and stress relieved Zr-2.5 Nb pressure tube material
containing deuterium between 5 and 200wppm was determined as per ASTM E− 1820-15 …

For the safety assessment of PHWR, it is required to study the flaw tolerance capacity of the
pressure tubes as a function of the loading rate. In this work, the effect of loading rate and …

The need for improvement of the in-reactor performance of Zr-2.5% Nb pressure tubes arose
because of the higher than expected diametral creep rates and variability in axial elongation …

The pressure tubes of Indian Pressurized Heavy Water Reactor (IPHWR) of 220 MWe are
made of Zr–2.5 Nb alloy manufactured either from Double Melted (DM) or from Quadruple …

Previous work by one of the authors reported the stress-field for a fully-constrained hydride
embedded in matrix computed using finite element method to develop an understanding of …

Fracture toughness and mechanical properties of the zircaloy-2 processed by rolling at
different temperatures have been investigated, and simulations have been performed using …

The tensile and fracture behavior of ultrafine-grained Al 6061 alloy has been studied by
experimental testing and extended finite element method simulation. The ultrafine-grained …

Abstract ASTM E1820-11, the most widely adopted standard for the determination of fracture
toughness parameters, recommends two ductile crack growth correction methods for the …

The tensile properties and fracture toughness of Zr-2.5 Nb pressure tube materials
manufactured for use in Indian PHWR220 and PHWR700 were evaluated. Tensile …
