To encourage the take-up of the outputs of JRP NEW04 by publishing a trade journal article describing a clear, well-defined method for users to evaluate thermal conductivity and associated uncertainties of the components of a TBC system from laser flash measurements. The method should be applicable to any layered material that can be measured using the laser flash technique. To remove a key barrier to uptake of the first objective by creating freely available software that automates the mathematically challenging aspects of the calculations, the software being promoted via the trade journal article and through other appropriate channels.
