Bending fatigue strength of nitrocarburized steel SS2244
Materials Science and Engineering: A, 1993Abstract Mean fatigue limit in rotating bending has been determined for the low alloy steel SS2244 in a gas nitrocarburized condition. Two nitrocarburizing treatments were used in which the nitrogen activity (aN) was either 700 or 2000. In both cases the carbon activity (aC) was unity and the notch factor (KT) 1.42.

Bending Fatigue Strength of WAAM Ultra-High-Strength Steel
Key Engineering MaterialsThis study investigates the bending fatigue strength of ultra-high-strength steel (UHS) steel manufactured using wire arc additive manufacturing (WAAM) technology. Hardness evaluations, conducted in the built direction, demonstrated a remarkable consistency with an average hardness of approximately 292 HV throughout the entire deposited component ...

Bending fatigue strength of carburising steel SS 2506
Materials Science and Technology, 1991AbstractThe effect of steel cleanness, core hardenability, and microstructure after carburising on bending fatigue strength is described for the standard steel grade SS 2506. Examination of the fatigue fracture surfaces revealed that initiation had occurred at the surface where an internally oxidised layer was present.

Microstructure and high bending fatigue strength in carburized steel
Journal of Heat Treating, 1989Cantilever fatigue specimens with a reduced section and rounded tensionside corners were machined from SAE 8719 steel (containing 0.19% C, 1.06% Mn, 0.52% Cr, 0.50% Ni and 0.17% Mo) bars. The specimens were plasma and gas carburized to surface carbon of 0.82% to 0.84%, surface hardness of 65 HRC, and case depths of 1.2 mm at 50 HRC. Some specimens were

[On fatigue bending strength of PMMA-specimen (author's transl)].
Archives of orthopaedic and traumatic surgery. Archiv fur orthopadische und Unfall-Chirurgie, 1981The fatigue response of PMMA-specimen was tested under cyclic bending of 1.5 Hz in a particularly designed testing device. Specimen were tested that a "Wöhler" curve and the corresponding fatigue strength could be evaluated. The fatigue strength was reached after a comparatively short time and ranged in the order of 33 per cent of static breaking ...
