Abstract

Abstract: A nanostructured surface layer with a mean ferrite grain size of ~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 ~40 nm at 973 K. Further increasing annealing temperature leads to an obvious reduction of ferrite grain sizes, to ~14 nm at 1173 K. The annealing-induced grain refinement is analyzed in terms of phase transformations in the nanostructured steel.

Key words: Nanostructured, Surface mechanical attrition treatment (SMAT), Ferritic steel, Grain refinement, Austenitization
