Summary on Grant Application Form |
IMPULSE will work with novel "MARBN" high temperature steel, recently developed in TSB project "IMPACT" and shown to
offer capability for an increase in steam power plant temperature of 25 K. IMPULSE, whose consortium includes most
IMPACT members together with new pipe, welding and innovative research partners, will take MARBN from the laboratory
on to full-scale industrial manufacture of ingot castings, pipework, and weldments. This will improve efficiency and reliability
of current and future steel-based steam power plant, and thus increase security of supply and reduce cost and carbon
emissions. MARBN 8-tonne ingot casting technology will be developed, and following high temperature (to 1250
degreesC+) testing and manufacturing simulation, two full-scale pipe extrusion trials will be undertaken, with product
validation by testing and electron metallography. Matching welding consumables will also be developed, qualified and
tested. Long term creep and creep-fatigue data generation will feed into performance validation, materials standardisation,
and pressure vessel design codes. Interaction with the KMM-VIN collaboration will enable constructive interchange with
parallel European projects.
The Birmingham team will characterise the grain structure and pinning particles in billet to be pierced and extruded into
pipe. A Gleeble thermo-mechanical simulator will compress samples representing this range of structures to varying strains
at temperatures and strain rates suitable for hot extrusion to determine the flow stress behaviour and resulting grain sizes
will be measured. Additionally, ring-shaped samples will be compressed (same temperatures and rates) between
instrumented tools to determine heat transfer and friction coefficients. These data will be used in an FE-based model to
simulate the extrusion process so that process parameters (temperature, strain and strain rate) to develop the correct
microstructure after welding and heat treatment can be determined.
