Abstract

The influence of various gaseous environments on the rate of fatigue crack growth at room temperature in an 0.45 percent carbon low-alloy ultra-high-strength steel tempered at 400°F and at 800°F has been investigated. The sensitivity of the rate of fatigue crack growth to moisture in this steel is found to be dependent on the fracture toughness of the material.

Résumé

L'influence de divers environnements gazeux sur le taux de croissance des fissures de fatigue à température ambiante d' un alliage à 0,451o de carbone d' un acier à très haute résistance trempé à 400 F. et à800 F.àétéétudiée.La sensibilité du taux de croissance des fissures de fatigue à l' humidité dans cet acier a été trouvée dépendre de la resistance à la cassure de ce matériau.

Zusammenfassung

Der Einfluss verschiedener Gasatmosphären auf die Zunahme von Ermüdungsrissen Raumtemperatur wurde untersucht an ultrahochfesten Kohlenstoffstahlen von niedriger Legieiung, welche bei 205 C. (400 F.) and 427 C. (800 F.) getempert wurden. Es wurde die Abängigkeit zwischen der Bruchstärke dieses Stables and der Einwirkung auf die Fortpflanzung von Ermudungsrissen durch Feuchtigkeit gefunden.
