TL;DR: In this paper, the effect of stress concentration at the notch of 18Ni2400 maraging steel on the tensile strength of cylindrical specimens has been investigated in air and synthetic seawater environments.

TL;DR: In this paper, slow strain rate tests were conducted in air and aqueous 0.6 M NaCl at −1.2 V SCE environments to investigate hydrogen embrittlement of ultra high strength 300 grade maraging steel.

TL;DR: In this article, a maraging steel, an ultra high strength steel, is welded using FSW process and it was observed that FSW joints demonstrated higher resistance to stress corrosion cracking (SCC) compared to both, base metal and gas tungsten arc weldments.

TL;DR: The microstructure, precipitation and mechanical properties of Ferrium S53 steel, a secondary hardening ultra-high-strength stainless steel with 10% Cr developed by QuesTek Innovations LLC, upon tempering were studied by scanning electron microscopy (SEM), TEM, X-ray diffraction (XRD), and tensile and impact tests as mentioned in this paper.

TL;DR: In this article, the effect of cathodic polarisation on stress corrosion cracking (SCC) behavior of peak-aged Ni(Fe, Al)-maraging steel in artificial seawater was investigated.

TL;DR: In this article, a backscatter diffraction analysis of a fractured steel specimen revealed that cracks initially propagated intergranulary along prior-austenite grain boundaries, and when cracks faced martensitic { 111 } α planes parallel to normal direction (ND), they were deflected and continued to propagate transgranular through { 001 } α / / ND planes.
