The department's specific research field is Phase Transformations in solid materials. On the basis of cutting-edge experiments we strive for developing models of phase transformations in bulk and nanomaterials (thin films). These models should not only provide fundamental insight into nature, but also be applicable in practice in order to optimize material properties by controlling the material microstructure. The department excels in the application of X-ray diffraction (XRD) methods, surface analytical methods (Auger electron spectroscopy (AES), X-ray photoelectron spectroscopy (XPS) and ellipsometry), and calorimetric and dilatometric methods. Also computer simulations of diffusion and phase transformations are an indispensable tool in our work.

Computer modeling of a phase transformation (austenite → ferrite in iron). The phase boundary in the figures moves from the right to the left.
Experimentally it would be difficult, if not impossible, to study the structure of the moving interface. Computer simulations can provide insight in transformation mechanisms.
