TL;DR: In this paper, it was shown that a wrought maraging steel P/M material with a strength in excess of 200,000 psi and substantial ductility can be made using conventional press and sinter techniques.
Abstract: The manufacture of maraging steel P/M parts is of interest for a number of reasons. Primarily, there are numerous potential applications for this high strength-high toughness type of material involving parts that could be most economically made by P/M techniques. With the 300,000 to 400,000 psi tensile strength range of certain wrought maraging steels, it is quite conceivable that a P/M material could be made with a strength in excess of 200,000 psi and with substantial ductility, using conventional press and sinter techniques.

TL;DR: In this paper, the authors studied the mechanical strength of maraging steel N18K9M5T after various variants of heat treatment and determined an optimum structure ensuring enough strength at high impact toughness and static and cyclic crack resistances.
Abstract: Characteristics of mechanical strength of maraging steel N18K9M5T after various variants of heat treatment are studied. The treatment mode providing a structure with retained austenite and two types of reverted austenite is determined. An optimum structure ensuring enough strength at high impact toughness and static and cyclic crack resistances is chosen.

TL;DR: In this paper, Austenite and martensite textures were studied in 18 pct Ni 350-maraging steel as a function of various degrees of cold rolling, and its effect upon microstructure and hardness has been studied.
Abstract: Austenite and martensite textures were studied in 18 pct Ni 350-maraging steel as a function of various degrees of cold rolling. The austenite phase in the samples was produced by repeated thermal cycling between ambient and 800 °C. The austenite phase thus formed was mechanically unstable and transformed to the martensite phase after 30 pct cold rolling. The texture developed as a result of cold rolling, and its effect upon microstructure and hardness has been studied.

TL;DR: In this article , a four-flute end mill made of maraging steel 1.2709 using a Concept Laser M2 Cusing Direct Metal Laser Melting (DMLM) machine was examined to determine its dimensional and geometric accuracy, surface roughness, and surface structure.
Abstract: This article considers the use of additive manufacturing to produce cutting tools for various machining operations, especially turning, milling, and drilling. The right geometry and material of the tool as well as coatings applied on cutting edges are crucial as they improve the life and performance of the tool. The study described here focused on a four-flute end mill made of maraging steel 1.2709 using a Concept Laser M2 Cusing Direct Metal Laser Melting (DMLM) machine. Before the printed tool was first used, it was examined to determine its dimensional and geometric accuracy, surface roughness, and surface structure. The measurement data showed that the tool required machining, e.g., grinding, to improve its geometry because the total runout of the shank and the cutting edge radius were too high, amounting to 120 μm and 217 μm, respectively. The cutting edges were sharpened to obtain a fully functional cutting tool ready to perform milling operations. The study aimed to check the dimensional and geometric accuracy of the 3D printed milling cutter and determine the optimal machining allowance for its finishing.
