Abstract

In this study, the three-dimensional arrangement of nm-scale precipitates in an Fe-20 at.%Mo alloy, aged at 500°C for 20 h, was resolved in three dimensions by 3D-atom-probe microscopy (3D-APM). It was found that the precipitates have an Mo concentration of about 90 at.% Mo, are 2-4 nm in size, and are arranged in chain-like structures along the 〈100〉-type directions of the bcc Fe-rich matrix.
