dc.description.abstract304L stainless steels with Hf additions were nanostructured by mechanical alloying (MA) and annealed at temperatures up to 1100 degrees C. The results showed that face-centered cubic (fcc) phase in 304L transformed to body-centered cubic (bcc) phase during MA. The in-situ studies revealed that bcc-to-fcc phase trans -formation completed after 105 min annealing at 900 degrees C for 304L, whereas Hf addition increased the required time and temperature for the complete transformation. The grain size of 304L stainless steel was-10 nm after MA and remained-167 and-293 nm after annealing at 900 and 1100 degrees C, respectively, with Hf addition in comparison to 960 nm average grain size of base 304L stainless steel after annealing at 900 degrees C. The hardness of 304L increased from-200 HV to 408 HV after MA and remained 329 HV after annealing at 1100 degrees C with Hf addition as opposed to 195 HV hardness of 304L.
