A comprehensive, standardised approach to high heat flux testing of materials is proposed, which allows for standardised data capture and comparison of measurements across global testing sites and setups. A meta-analysis of data for tungsten, with data re-captured in that format, highlights interesting trends with respect to appropriate damage metr…

Within a tokamak fusion energy device, the performance and lifespan of a divertor monoblock under high heat flux cycles is of particular interest. Key to this is the quality of manufacture, especially the material joining interfaces. Presented here is a comparative study between X-ray and neutron tomography to investigate the quality of manufacture…

An investigation has been carried out to verify if the strain rate sensitivity effect of 316 steel material can be measured using the small punch test method. It was found that the effect was observed during small punch testing over a displacement rate range of 0.0125 – 1.25 mm/min, with maximum load increasing as the rate increased, and the stra…

Fusion demonstration (DEMO) concepts are facing challenges in safety and licensing in part due to uncertainties with in-vessel components validation, which relate directly to the materials and design criteria used for assessments. These challenges come from the designed operation under unprecedented environmental conditions and reliance on the perf…

The microstructure and thermal stability of V-4Cr-4Ti-1.8Y-0.4Ti3SiC2 alloy, fabricated by 60 hr mechanical milling of blended powders followed by spark plasma sintering (SPS) and hot isostatic pressing, has been investigated. Analysis was undertaken using orientation image maps obtained from the electron backscattering and transmission Kikuchi dif…

The development of new, high-performance reduced activation materials is increasingly recognised as one of the key enabling technologies required for the advancement of civil fusion power. To comply with the fusion ethos of no material entering the permanent active waste disposal route, reduced activation steels have been developed and are consider…
