Nano Structured MaterialsIEHK
The group of Nano Structured Materials aims at developing new concepts of alloy and microstructure design for enhanced material performance by applying a combined experimental and simulation tools. Advanced characterization approaches, like atom probe tomography (APT), in situ high energy synchrotron X-ray diffraction (SYXRD) and small angle neutron scattering (SANS) are employed to analyze the nano structures in the materials.
The mechanisms of the phase transformations and deformation behaviors in materials are the main target to explore by means of nano-scale characterization combined with various simulation tools, for example ab initio theoretical calculation, CALPHAD method, phase field simulations, etcetera. The understanding of these mechanisms in the materials is up-scaled to micro- and macro- level. The current research interest is focusing on the TRIP/TWIP/MBIP high Mn and medium Mn steels, the microstructural damage during rolling contact fatigue of bearing steels, the intermetallics in steels for enhanced strength and ductility, the high entropy alloys, the understanding of ordering effect and its contribution to the mechanical properties in various alloys.
