Thermomechanical Properties of Thin α-Fe Films Above the Brittle to Ductile Transition Temperature


In this contribution, we present first results on the microstructure and thermomechanical properties of bcc iron films on sapphire substrates produced with the molecular beam epitaxy technique. Thermomechanical properties were measured with a substrate curvature system in an ultra high vacuum (UHV) environment above room temperature up to 540°C, while the micro-structure of the films was analyzed by X-ray diffraction and microscopic methods. The results are compared to measurements with fcc metals.
