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.
