Fig. 3: Atomic configuration and fracture mechanisms of sulfur segregation at the oxide-matrix interface.
From: Unveiling the atomistic mechanism of oxide scale spalling in heat-resistant alloys
a Filtered iDPC image and an intensity line profile taken across the scale-matrix interface (orange line). b A simple oxide-matrix interface, similar to a, constructed by a DFT simulation. c Change of Gibbs free energy as sulfur diffuses from the matrix to the interface. d The 2D ELF maps and e PDOS curves between typical S atoms and other nearest atoms (Al and O). f iDPC imaging and g EDS mapping analysis of the detached scale region. Source data are provided as a Source Data file.
