Microstructural characterization of Mg–Al–O rich nanophase strengthened Fe–Cr alloys

Fe–9Cr ODS alloys elaborated by mechanical milling (MM) and followed by hot isostatic pressing (HIP) and hot rolling (HR) have been studied using transmission electron microscopy (TEM) and atom probe tomography (APT) to understand their microstructural characterization. The as-HIP alloy exhibited equiaxed ferrite and contained nanoparticles and low density of dislocations. The as-HR alloy manifested elongated ferrite and contained nanoclusters...
