“…However, these observations agree well with Chezan et al [11], in which they reported that the severe deformation caused by cold rolling for Fe-Ni-Ti and Fe-Ni-Cr leads to formation of large density nucleation sites for new phases, i.e. γ ′ and ε.…”

The nitriding behavior of cold rolled Fe 93 Ni 4 Ti 3 specimens was compared with that of hot rolled specimens of the same materials. Radio frequency (rf) nitriding was performed for 10 minutes in a 10 -2 mbar nitrogen atmosphere. The continuous plasma power was varied from 300-550 W in steps 50 W or less. Results of optical microscopy (OM), x-ray diffraction (XRD) and microhardness measurements (Hv) are presented and discussed with regard to the influence of kind rolling on the nitriding behavior, particularly nitride formation and nitride layer growth on mechanical properties. The results show a remarkable increase of nitrogen diffusivity and microhardness of cold rolled nitride samples. These best results may be attributed to enhancement of the defect and/or a compressive stress.

“…6 The synthesis of nanocrystalline stainless steel, which is a very important material due to its excellent corrosion resistance, has also been investigated, aiming at further improvement of its mechanical properties. The synthesis techniques employed for nanocrystalline stainless steel so far include bulk nanocrystalline synthesis by in situ consolidation, 7 the grain refinement of the cold-rolled foil via phase transformation cycling during gaseous nitriding, 8 surface nanocrystallization by sand blasting, 9 surface mechanical attrition [10][11][12][13] and ultrasonic shot peening. 14 It has been reported that the hardness and the yield strength of such nanocrystalline stainless steels are superior to those of the coarse-grained stainless steel.…”

The FeCrNi alloy, whose composition is close to that of stainless steel 304, was prepared by electrodeposition and characterized. Nanocrystalline FeCrNi (nc-FeCrNi) was obtained by employing a double-compartment cell where the anode is separated from the cathode compartment, while amorphous FeCrNi (a-FeCrNi) was deposited in a conventional single electrochemical cell. The carbon content of nc-FeCrNi was found to be significantly lower than that of a-FeCrNi, suggesting that carbon inclusion is responsible for the change in the microstructure. The major source of carbon is associated with the reaction compounds at the anode electrode, presumably decomposed glycine. Crystal structure analysis by XRD and TEM revealed that the as-deposited nc-FeCrNi deposits consist of α-Fe which transforms to γ-Fe upon thermal annealing. Nanoindentation tests showed that nc-FeCrNi exhibits higher hardness than a-FeCrNi, which is consistent with the inverse Hall-Petch behavior.
