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.

Abstract This article discusses the effects of alloying on the properties and behaviors of maraging steels. It describes how maraging steels differ from conventional steels in that they are strengthened, not by carbon, but by the precipitation of intermetallic compounds.

Metal Science and Heat Treatment, 1966
1. Small grained maraging steel has a higher ductility than the large grained steel but in a number of cases the influence of the grain size is masked by other singularities of the steel. 2. Extracted carbon replicas of the surfaces of the fractures of steel samples with the highest ductility are free from intermetallic and nonmetallic ...

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°.

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.

Hydroerosion resistance of maraging steels
Metal Science and Heat Treatment, 19721. 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.

Phase composition of maraging steels
Metal Science and Heat Treatment, 19691. 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

A high-strength maraging steel
Metal Science and Heat Treatment, 1993Maraging 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 ...

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,
