“…[8,9,42,85,86], can be viewed in the vein of earlier considerations by Gough [87], Dehlinger [88] and Hempel and co-workers [58,60]. The evidence suggests strongly that the physical origin of the fatigue limit of a-iron is related to the b.c.c, structure, as suggested previously by Ferro and co-workers [82,83], Wood and co-workers [28], Adair and Lipsitt [84], BergstrSm and co-workers [32] and by ourselves [7-9, 15, 42]. However, the "characteristics" of the fatigue limit, cf.…”

strongly impeded dislocation multiplication below Aept -5 × 10 -4, appreciable secondary slip at higher Aepl leading to a cell structure (persistent slip bands do not form), shape changes due to asymmetric slip of screw dislocations and a relatively high effective stress level.The reduction of ~p~ and the presence of solute carbon atoms modify this behaviour significantly, making it more similar to that of f.c.c, metals. In all cases it was found that only the athermal component of the peak (saturation) stress but not the latter itself represents a suitable measure of the properties of the dislocation substructure.On the basis of the cyclic deformation behaviour and of observations of trans-and intergranular fatigue crack initiation it was concluded that the fatigue limit of a-iron is an intrinsic property of the b.c.c. structure whose characteristics, however, are affected sensitively by interstitial impurity content and by the strain rate of the fatigue test.

“…Bei den kubisch-flachenzentrierten Werkstoffen wie beispielsweise Aluminium, Kupfer und ihren Legierungen, ist diese asymptotische Annaherung nach sehr hohen Lastspielen verschoben (7). Bei Kupfer-Zinn-Legierungen ist beispielsweise auch nach 109 Lastspielen noch kein horizontaler Auslauf der Wohlerkurve festzustellen (8)…”

Die Biegewechselfestigkeit von verschieden wärmebehandelten Mehrstoff‐Kupfer‐Aluminium‐Legierungen wurde in Luft, in destilliertem Wasser und künstlichem Seewasser mittels glatter und gekerbter Proben bestimmt. Die Korrosionswechselfestigkeit liegt für künstliches Seewasser am niedrigsten. Ein Einfluß des Gefüges ist in nur geringem Maße vorhanden. Weniger stark beeinflußt destilliertes Wasser die Korrosionswechselfestigkeit. Bei den Versuchen in Luft ist eine Abhängigkeit vom Gefüge vorhanden. Gekerbte proben mit bestimmten Formziffern ergeben bei Biegewechselversuchen an Luft teilweise höhere Werte als glatte Proben. Dieser anomale Kerbeinfluß verschwindet bei zusätzlicher Korrosion.

“…A scientific approach to the question of fatigue strength would be to consider the effects of crystal structure on fatigue mechanisms [1][2][3][4]. Researchers from the field of fatigue are aware of the ratio between endurance limit and ultimate tensile strength, Se/Rm (see Figure 1).…”

“…Interestingly, nonferrous materials exhibit a gradual flattening between 10 7 -10 8 cycles. Although some researchers have explained these effects in terms of strain ageing and dislocation locking (see [4]), there is also evidence that the involved crystal structure plays an important role [1,2].…”

Simulation-based Understanding of the Critical Resolved Shear Stress Relevance for the Fatigue Performance of Metallic Materials

The paper introduces a valuable new description of fatigue strength in relation to material properties and thus a new perspective on the overall understanding of the fatigue process. Namely, a relation between the endurance limits and the accompanying values of the critical resolved shear stress (CRSS) for various metallic materials has been discovered by means of a multiscale approach for fatigue simulation. Based on the uniqueness of the relation, there is a strong indication that it is feasible to relate the endurance limit to the CRSS, and not to the ultimate strength as often done in the past.
