摘要	A nanostructured surface layer with a mean ferrite grain size of similar to 8 nm was produced on a Fe-9Cr steel by means of surface mechanical attrition treatment. Upon annealing, ferrite grains coarsen with increasing temperature and their sizes increase to similar to 40 nm at 973 K. Further increasing annealing temperature leads to an obvious reduction of ferrite grain sizes, to similar to 44 nm at 1173 K. The annealing-induced grain refinement is analyzed in terms of phase transformations in the nanostructured steel.
