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.

Low Nickel Maraging Steel

2013
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.

Mechanical Properties Of Maraging Steels

Euro PM2025 Proceedings
Maraging steels are a class of high-strength iron alloys of very low carbon content and in many cases, the materials of choice in applications that require high corrosion resistance. In this paper, mechanical tests of hardness and electrochemical characterization of maraging steel obtained by the 3D-printed were carried out.

The Sintering of maraging steel with phosphorous additions

The aim of this thesis was to investigate densification and microstructural development of loose packed, 200-grade maraging steel, sintered with ferro-phosphorous additions. This was achieved by characterising the sintered density and hardness of compacts with various phosphorous concentrations, after sintering in nitrogen, argon and vacuum atmospheres

Metallography and Microstructures of Stainless Steels and Maraging Steels

2004
Abstract 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 ...

The physical metallurgy of maraging steels

International Materials Reviews, 1968
AbstractMaraging steels are a class of high-strength steels characterised by very low carbon contents and the use of substitutional elements to produce age-hardening in iron–nickel martensites. The term 'maraging' was coined from a combination of martensite and age-hardening.

Maraging steel with reduced cobalt

Metal Science and Heat Treatment, 1968
1. Maraging steels are characterized by a good combination of strength, plasticity, and ductility, and low notch sensitivity and susceptibility to brittle fracture at low temperatures. Nickel-molybdenum-cobalt steels have the best combination of properties. 2. Maraging steels with a strength of 150 kg/mm2 are best alloyed with 4.0\2-5.0%
