The maraging-steel blades of the Virgo super attenuator

Measurement Science and Technology, 2000
The 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, 1968
1. 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, 1974
1. 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°.

Hydroerosion resistance of maraging steels

Metal Science and Heat Treatment, 1972
1. The erosion resistance of the steels investigated is highest after heat treatment ensuring maximum strengthening. 2. Cold treatment with subsequent aging increases the hardness and the erosion resistance.

Nitriding of maraging steel N18K9M5T

Metal Science and Heat Treatment, 1971
1. 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,

A high-strength maraging steel

Metal Science and Heat Treatment, 1993
Maraging steel 02N18K3M3T, which has essentially the same strength and reliability as commercial steel 02N18K9M5T, has been developed on the basis of laws revealed for the influence exerted by alloying elements, modifiers, and deoxidizers on the phase composition and production and mechanical properties of high-strength maraging steels, as well as a ...

Phase composition of maraging steels

Metal Science and Heat Treatment, 1969
1. The highly dispersed hardening phase (Fe, Ni, Co)2Mo is formed during aging of steels N17K9M5 and N18K9M5T at 550–640°C. 2. Besides the intermetallic phase based on Fe2Mo, the η Ni3Ti phase with a hexagonal lattice is formed in steel N18K9M5T at 600–640°C. 3. In steels N15, N17, N18K9, N17K9M5, and N18K9M5T tempered in the

On Reliability of Stainless Maraging Steel

Solid State Phenomena, 2017
The investigation results on the problem of the reliability of high-strength low-carbon maraging steel products have been generalized. The influence of a method for remelting on the reliability behavior is shown and the ways for the reliability behavior improvement are suggested.

Maraging Steels

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

2014
Abstract 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.
