Residual stress mapping within creep resistant DC cast Magnesium alloy slab
We aim to use the ENGIN-X facility to measure the residual field within an industrial scale (1 x 0.8 x 0.3 m), direct chill (DC) cast slab of a high strength, creep resistant... -
Residual stress distributions and stress relaxation due to Post Weld Heat Tre...
UK power plants are following the worldwide trends in the power generating industry, in line with demands for increases in the efficiency of existing power plants and for... -
Slow strain rate sensitivity of anelasticity in 316H stainless steel
In order to understand the consequences of load and unload dwells on power plant materials behaviour at high temperature it is necessary to develop a fundamental understanding... -
Residual Stresses in Tekken Weld Specimen
Approved proposal under the ICRD Scheme Proposal ICRD0017 -
Validation of the asymmetric cut in the contour method.
The Contour method is a powerful residual stress measurement method, that is still under development. A limitation of the technique is that the component must be cut into two... -
Interaction between Residual and Applied Stresses in Dissimilar Metal Welds
This proposal, that is part of the Bristol-Open University-ISIS long term programme, is to undertake a series of neutron diffraction experiments to gain an understanding of the... -
Random and Systematic Errors in Measuring the Lattice Parameters of a Dissimi...
Dissimilar metal weld (DMW) joints are widely used in nuclear power plants to connect ferritic steel components with austenitic steel piping systems. AREVA has designed a new... -

Intergranular stress generation during high temperature creep-fatigue loading
Intergranular stresses, generated during cyclic loading of AISI type 316H stainless steel can significantly affect the creep deformation of this material. However,... -
Study of creep cavitation in a waisted creep test specimen
The life of modern power generating plant is limited by the high temperature performance of the materials from which it is constructed. The drive for longer operating lives, and... -
Residual stresses in ultrasonically-peened welded joints
Ultrasonic peening (UP) can improve the fatigue resistance of welded joints by introducing compressive residual stresses at the toe of the welds, and offers significant... -
Effects of plastic pre-strain on residual stress in welded steam tubing
Power generation plant heat exchangers contain many banks of thin section, small diameter boiler tubes that are usually cold bent to shape (introducing high levels of plastic... -
Fabrication Residual Stresses in Boiler Bifurcations
Recently, a number of creep cracks have been found in complex pipe to pipe intersections, referred to as bifurcations in the boilers of the UK¿s Advanced Gas Cooled Reactors...
