Accelerated atomic-scale exploration of phase evolution in CCSS systems using combinatorial processing platforms (B01)

• Subject Area: Thermodynamics and Kinetics as well as Properties of Phases and Microstructure of Materials ; Physical Chemistry of Solids and Surfaces, Material Characterisation
• Term: since 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 506711657

B01 aims to assess the phase stability of new CCSS, select thermally stable single-phase CCSS among many candidates in an accelerated manner, and provide additional data on surface segregation, surface composition, as well as grain boundary segregation of selected CCSS at different temperatures. These data will contribute to other CRC projects for further in-depth studies on smooth (large-grained) CCSS in order to understand and control their SAA. To achieve these goals, B01 will use the combinatorial processing platform (CPP) approach, comprising APT, TEM and correlative APT/TEM, to perform near-atomic-scale analyses of 3D elemental distribution and crystal structure.
