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...

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...

Bio-oil can be obtained from the pyrolysis of biomass and maintains a closed carbon cycle with no net increase in atmospheric CO2 level, making the environment cleaner. However,...

In our research programme the overall goal is to explore how residual stress/strain infulences thedeformation and fracture behaviour of engineering steels at high temperatures....

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...

Fracture prediction of structures manufactured from high strength engineering steels is a high priority in key industries. In this work residual stress (RS) effects on creep...

The stress corrosion cracking (SCC) of austenitic stainless steels (ASS) has been shown to increase with cold work (CW). However, the mechanism by which CW and the subsequent...

We ask for 3 days on TOSCA to conduct Inelastic Neutron Spectroscopy on potassium/sodium encapsulated in silica gel materials (K2Na-SG) and for in situ formation of...

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...

The proposal aims to examine how introducing 8% plastic strain in 316H steel through precompression, influences the intergranular strains in the material when loaded parallel...

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...

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...

In the course of 2.5 years research in Cambridge, we have developed for the first time a tough, low-carbon martensitic stainless steel weld metal (CamAlloy 4) which can be used...

In our research programme the overall goal is to explore how residual stress/strain influences the deformation and fracture behaviour of engineering steels at high temperatures....

For some engineering purposes like welding or SCC where IGS (Inter Granular Stresses) increase susceptibility to cracking, some indicator of the level of plastic deformation...

Oxford University in collaboration with ISIS neutron facility have developed a new technique for imaging strain in engineering components in three dimensions. We termed this...

Welding-induced distortions and residual stresses of structural components can result in significant increase in manufacturing costs and then limit the development of innovative...

The investigation is aimed to confirm the non-diffusive process known as strain-induced martensite formation which could manifest itself in Duplex Stainless Steel (DSS) during...
