Abstract

The microstructure of NiAl-type (β′) precipitates in an aged ferritic steel (Fe-12.7Al-9Ni-10.2Cr-1.9Mo, at.%) is characterized by transmission and analytical electron microscopy (AEM) and atom probe tomography (APT). The alloy shows a duplex precipitation of β′ particles: primary with an average diameter of 130 nm and secondary with an average diameter of 3 nm. Based on APT, the primary and secondary β′ have compositions of Ni_41.2Al_43.6Fe_12.7Cr_0.8Mo_1.4 and Ni_26.3Al_41.6Fe_26.9Cr_3.3Mo_1.7, respectively.
