“…The tensile stress-strain curves as well as those of the strain controlled fatigue tests have been published earlier [11,20,27]. In combination they reveal that for the transformation-induced plasticity group the endurance does not relate to the carbon + nitrogen-content, Figure 3a.…”

“…The nickelcontaining steels CrNiMnCN0.12, CrMnNiCN0.11, CrNiMnCN0.2 as well as the Hadfield-steel were cast while all others were forged. All steels were solution-annealed and quenched before any metallographic analyses and mechanical tests, which resulted in the properties given, Tables 3, 4 [11,20].…”

“…Chromium-nickel-carbon-nitrogen (CrNiCN) steels show wavy slip under fatigue leading to the generation of dislocation cells. By increasing the nitrogen-content up to 0.4 wt.% more planar slip takes place but the wavy slip part still rules the cyclic properties for example under reciprocating sliding wear [10,11]. In general such steels show a cyclic hardening behavior, while the CrMnCn steels always exhibit planar slip and cyclic softening [9].…”

Austenitic high nitrogen (AHNS) and austenitic high interstitial steels (AHIS) are of interest for mechanical engineering applications because of their unique combination of mechanical (strength, ductility), chemical (corrosion resistance) and physical (non-ferromagnetic) properties. But despite their high strength values e. g. after cold deformation up to 2 GPa in combination with an elongation to fracture of 30 %, which is based on twinning-induced plasticity (TWIP) mechanisms and transformation-induced plasticity (TRIP) mechanisms, the fatigue limit remains relatively small. While for chromium-nickel steels the fatigue limit rises with about 0.5-times the elastic limit it does not at all for austenitic high-nitrogen steels or only to a much smaller extent for nickel-free austenitic high-interstitial steels. The reasons are still not fully understood but this behavior can roughly be related to the tendency for planar or wavy slip. Now the latter is hindered by nitrogen and promoted by nickel. This contribution shows the fatigue behavior of chromium-manganese-carbon-nitrogen (CrMnCn) steels with carbon + nitrogen-contents up to 1.07 wt.%. Beside the governing influence of these interstitials on fatigue this study displays, how the nitrogen/nickel-ratio might be another important parameter for the fatigue behavior of such steels.Keywords: Austenitic high strength steels / Ramberg-Osgood / twinning-induced plasticity (TWIP) / transformation-induced plasticity (TRIP) / nitrogen-nickel ratio / cyclic behavior Schlü sselwö rter: Austenitische hochfeste Stä hle / Ramberg-Osgood / durch Zwillingsbildung induzierte Plastizitä t (TWIP) / umwandlungsbewirkte Plastizitä t (TRIP) / Stickstoff-Nickel Verhä ltnis / zyklische Belastung Corresponding author: S.

FeCrMnCN stainless austenitic high-interstitial steels (HIS) combine the properties of conventional FeCrNi austenites (superior ductility and surface corrosion resistance) with the potential of significant strengthening. This combination of properties makes them promising candidates for environments that require resistance to both wear and corrosion, e.g., processing of plastics. The aim herein is to make use of the high work-hardening ability of HIS. Thus, machined preforms with an application-related design are formed by profile cross rolling. The preform design enables a hardness increase in component regions that are most subjected to wear. Rolling of the specimens results in a very high surface quality with a roughness Rz in the range of 1 μm. Hardness measurements in rolled specimens confirm a significant hardness increase in the subsurface up to a depth of %2.5 mm. Hardness values of about 600 HV1 are yielded within a surface distance of %0.3 mm. Furthermore, tests on a modified pin-on-disc tribometer suggest that the wear behavior of the work-hardened HIS is comparable with nitriding steel. Thus, the results of this study support the development of a forming technology for screws in corrosive environments.
