Atomic-scale study of second-phase formation involving large coherency strains in Fe-20 at. pct Mo

The 3D alignment of the decomposition microstructure in Fe-20 at. pct Mo is investigated by 3D atom probe microscopy. This technique reconstructs in three dimensions a specimen volume of typically 15 x 15 x 50 cu nm based on the spatial coordinates and the chemical identity of each detected atom. Th...

Description
Summary:The 3D alignment of the decomposition microstructure in Fe-20 at. pct Mo is investigated by 3D atom probe microscopy. This technique reconstructs in three dimensions a specimen volume of typically 15 x 15 x 50 cu nm based on the spatial coordinates and the chemical identity of each detected atom. The results confirm the formation of a metastable Mo-rich phase upon annealing at 500 C. (AIAA)
