Hydrogen embrittlement of maraging steel
Journal of Materials Science, 1992Specimens of 18 Ni 1800 MPa (M250) grade maraging steel were charged with different quantities of hydrogen by an electrochemical method. The tensile properties and fracture characteristics have been correlated with the quantity of hydrogen picked up by the material.

Phase transformations in maraging steels
2012Research on the kinetics of precipitate formation and austenite reversion in maraging steels has received great attention due to their importance to steel properties. Judging from the literature in recent years, research into maraging steels has been very active, mainly extending to new types of steels, for new applications beyond the traditional ...

The maraging-steel blades of the Virgo super attenuator
Measurement Science and Technology, 2000The blades are crucial components of the Virgo super attenuators. The material used for their construction is maraging steel, a low-carbon-content alloy with high ultimate tensile strength and low creep under stress. Young's modulus, the shear modulus, the Poisson ratio and the corresponding elastic energy-loss coefficients have been measured.

The ??? transformation in maraging steel N18K9M5T
Metal Science and Heat Treatment, 19681. The α→γ transformation in steel N18K9M5T occurs on holding at 500–730°C or on heating at rates below 30–50 deg/sec by way of martensite decomposition in the two-phase α+γ region with redistribution of alloying elements between ferrite and austenite. 2.

Radiation resistance of maraging steel
Metal Science and Heat Treatment, 19741. The radiation resistance of maraging steels is superior to that of pearlitic steels. After irradiation with an integral neutron flux of 8·1020N/cm2 at 70–100° the ductile-brittle transition temperature of the pearlitic steel rises from −80 to +100°, while that of the maraging steel remains below −80°.

Abstract This article presents fractographs of maraging steels that failed by overload, fatigue, and embrittlement. A small sampling of fractographs in the article illustrates the slow-bend fracture of a weld specimen produced by gas tungsten arc butt welding two 19-mm (3/4 in)-thick plates of 18% Ni maraging steel with a yield ...

Heat Treating of Maraging Steels
2014Abstract Maraging steels are highly alloyed low-carbon iron-nickel martensite steels that possess an excellent combination of strength and toughness superior to that of most carbon-hardened steels. This article provides a detailed account of the formation of martensite in maraging steels.

The kinetics of precipitate formation are analysed using the Johnson–Mehl–Avrami (JMA) theory. Nano-sized precipitates are formed homogeneously during the ageing process, which results in high hardness. As the ageing time is prolonged, precipitates grow and hardness increases.

Nitriding of maraging steel N18K9M5T
Metal Science and Heat Treatment, 19711. Nitriding of maraging steel N18K9M5T results in the formation of a case that is not brittle and is firmly bonded to the base metal, with a depth of 0.2–0.25 mm and a high surface hardness (up to HV 900). 2. Nitriding greatly increases the wear resistance of the steel and also the fatigue limit. 3. After aging and nitriding,

Metallography and Microstructures of Stainless Steels and Maraging Steels
2004Abstract This article describes metallographic preparation and examination techniques for stainless steels and maraging steels. It presents a series of micrographs demonstrating microstructural features of these alloys. Procedures used to prepare stainless steels for macroscopic and microscopic examination are similar to those used for ...
