Stresses in a Dissimilar Metal Weld Pipe Butt Weld
Stress corrosion cracking is an important degradation mechanism that is threatening the structural integrity of pressurised water reactors throughout the world. AREVA has... -
Residual stresses in a ring weld specimen after extended creep relaxation
Reheat cracking is a failure mechanism seen in welds fabricated from high temperature creep resistant materials. A new feature test specimen (ring-weld) has been designed to... -
Creep Cavitation in Stainless Steel Weldments
Reheat cracking is a creep failure mode that has been observed in welded structures operating at high temperatures in the power generation industry. The failure results from the... -
NET Round Robin Measurements of 3-Pass AISI316 Welded Plate Samples
This work is part of a round robin exercise in residual stress standardisation as part of the NET programme. Within the NET programme, multiple simulations of the weld stress... -
Effect of Anelasticity on Creep Behaviour
Nuclear power generation plants undergo start-up/shut-down load-temperature cycles during service operation. Components operating at temperatures in the creep regime can exhibit... -
Effect of PWHT on Lattice Parameters of a Dissimilar Metal Butt Weld
Stress corrosion cracking is an important degradation mechanism that is threatening the structural integrity of pressurised water reactors throughout the world. Dissimilar weld... -
Development of Creep Cavitation in Stainless Steel

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... -
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... -
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... -
Residual stresses in laser welded benchmark specimens to validate a new plast...
A novel analytical approach has been developed to assess the plasticity induced error in residual stress (RS) distributions measured by the contour method (CM) for which... -
The Origin of Anelastic Creep Behaviour
Nuclear power generation plants undergo start-up/shut-down load-temperature cycles during normal service operation. Components operating at temperatures in the creep regime can... -
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... -
