TLDR
In this paper, an 18Ni (300-grade) maraging steel at room temperature in dry and humid argon environments (atmospheric pressure) was examined to examine the effect of moisture on the rate of fatigue-crack propagation and on the fracture path through the microstructure.About:

The effect of air and vacuum environments on fatigue crack growth rates in Ti-6Al-4V
Phil E. Irving,C.J. Beevers +1 more
TL;DR: In this paper, the authors proposed a mechanism for the structure sensitive mode of fatigue crack growth in vacua of 1.33 mN m-2, on Ti-6 A1-4V, at growth rates of 10-7 to 10-4 mm/cycle.

Fracture mechanics : integration of mechanics, materials science, and chemistry
TL;DR: In this paper, fracture and slow crack growth reflect the response of a material (i.e. its microstructure) to the conjoint actions of mechanical and chemical driving forces and are affected by temperature.

Generalized theory of fatigue crack propagation: Part II — Derivation of threshold and Paris regime crack growth rates
TL;DR: In this paper, the growth rate of fatigue cracks by the continuous advance of the crack front normal to itself, as well as by the discontinuous ledge-controlled processes, were derived in the presence and absence of strong crystallographic constraints on crack front motion.

Acceleration of crack growth under intermittent overstressing in different environments
TL;DR: In this article, the authors investigated fatigue crack growth behavior under intermittent overstressing in low carbon steels under tension-compression loading with a few tests under compression-tension loading and found that a small number of cycles of overstress applied intermittently during a very large number of understress below threshold caused significant acceleration, of about one hundred times, in crack growth rate as compared to the case of steady cyclic stress.

Fatigue Behavior of 18% Ni Maraging Steels: A Review
TL;DR: In this paper, a critical review of studies reported in the published literature aiming to improve the fatigue life of 18% Ni maraging steels is presented, which suggests that fatigue strengths higher than those realized in peak aged condition can be obtained through controlled overaging with a small amount of reversed austenite playing a critical role.

A unified structural mechanism for intergranular and transgranular corrosion cracking
W. D. Robertson,A. S. Tetelman +1 more
TL;DR: In this article, a unified, structural mechanism is proposed to explain the phenomena of intergranular and transgranular stress corrosion cracking, and the dependence of failure on composition and stress in copper alloys and in stainless steels is analyzed.
