The existence of the critical grain size Dc for reconstructive martensitic transformations implies that at austenite grain diameters D smaller than Dc the transformation is suppressed during cooling down to absolute zero temperature. In the case of athermal macrokinetics, martensite crystals divide connected (free from boundaries) volumes of austen...

The increasing emission of CO_2, due to the growing power consumption, requires more and more efforts to replace fossile fuels by sophisticated no-emission systems in power generation. Using photovoltaics is one possible option. Producing electricity by solar energy, photovoltaics may contribute to a significant reduction of CO_2 emissions. The bas...

The present work examines the failure mechanisms of TBC-coated systems during cyclic temperature exposure without additional mechanical load in the temperature range between 900 C and 1050 C. If failure appeared until an testing duration of 5000h in the temperature range between 900 C and 950 C, it was driven by the formation of a brittle chromium-...
