Abstract :
The effects of oxygen variations on 14(Cr)YWT(Ti) nanostructured ferritic alloys (NFA) containing high densities of Y–Ti–O nano-features (NFs) were investigated using transmission electron microscopy, atom probe tomography and small angle neutron scattering. The alloy with the lowest O had the fewest and coarsest NFs. The microhardness increase with higher O content is consistent with the corresponding increasing NF volume fraction and variations in grain size.
